ABSTRACT

Nine volatile corrosion inhibitor (VCI) concentrateswere evaluated in eight selected base oils to determinethe feasibility of utilizing a VCI concentrate to improvethe preservative properties of operating lubricants.

The work reasonably demonstrated the feasibility ofusing carefully selected concentrates to improve thepreservative properties of an operating lubricant.However, unpredictable compatibility problems may preventa practical application of this process.

Three promising concentrates were found that wouldprovide vapor phase protection comparable to that ofSpecification MIL-L-46002 VCI oil, and exhibited onlyslight sedimentation in compatibility tests with operatinglubricants. Of the three, only one had the supply andlogistics properties deemed to be most desirable.

It was revealed that concentrates in liquid formwere best suited because solubility problems wereencountered with the powdered form of concentrate.

Tae type of diluent which is part of the concentratecan also produce detrimental effects on a product whenit iz added to a. operating oil as evidenced by drasticchanges in viscosity, pour point and flash point.

RECOMMENDATIONS

It is recommended that a pilot test be conductedwhenever a VC! oil concentrate iq to be blended with afinished pr,.CwT to insure that the specZ'tic combinationis comr atible and will not adversely affhct the equipmeaitinvolved.

It is recommended that consideration be given to thefurther investigation of this basic concept by thefollowing:

1. Determine the effects of oxidized oils, or oilswhich have been in storage for a considerable period oftime, on the protection, compatibility, and physicalcharacteristics of the oil-concentrate mixtures.

2. Determine the causative effects of the incom-patibilities which exists between MIL-L-2104, Grade 30oil and the VCI concentrate during long term storage.

3. Determine if an inhibitor in a solvent-baseconcentrate can be effectively iitili7ed in an oil baseconcentrate.

4. Initiate engine storage tests on the effectiveVCI concentrates to ascertain their value in actualservice.

5. Determine the long term storage characteristicsof unused, undiluted VCI concentrates.

6. Determine the most desirable dilution ratio toprovide an optimum protection level for use with engine,hydraulic, or general purpose lubricants

INVESTIGATION OF VOLATILE CORROSION INHIBITORADDITIVES FOR STANDARD OPERATING OILS TO IMPPOVE

THEIR PRESERVATIVE CHARACT:LISTICS

OBJECT

To determine the practicalily ar.d feasibility of up-grading the protection characteristics o:2 standardoperating lubricants and hydraulic oils oy the additionof a volatile corrosion inhibitor (VCI) concentrate.

INTRODUCTION

Military equipment and machinery is normallysubjectd: '.-- :-ying peril'%: cf I.i:tciittont operationduring its life The satisfactory storage ana pro-tection afforded the closed lubricant and hyara.ilicsystems of such equr.-nent during nr.n-use periods is ofprime importance because inadequate protection againstcorrosion can result in costly rzpairs, and undesirabledowrcime. Moreover, the lar-k of protection may resultin equipment faalures under extremely critical serviceconditions.

Basically, in a closed l.ubrication system suchas engine crankcases, tranmissions. or hydraulicsystems, the oil will, in non-use perios, tend todrain off the upper and vertical surtaces to thenormal oil level, leaving areas with inadequate pro-tection. Conventicnal contact inhibitors, such assulfonates, amines, or fatty acid derivatives, protectonly when in direct contnct w:,th a surface. 'hedrained areas are thus sub~ec* to corcosion daunage,and in systems with delicate op rational mechanis:nsor critical surfaces even very slIght corrosion canresult in decreased ffficlency, malfunctions, or evennon uperation. The corroýI.iu,, prctecti.n ui buch areasor systems would be greativ ,,,nprovec it the drainagecharacteristics of the usual p-eservative oils couldbe modified or mninimized This. however, is not possibleto any acceptable degree at tUi•" pAesent time. Asimilar effect can, however. n, -chieveu if the preser-vative oil contains, in additior tc tne contactinhibitors, a volatile inhilbitor which will producerust inhibition within the ciuscd sy)stcm witihouýdirect contact of oil and surlace Sucni a , on;itionhas beer 'roduced in the past with certain volatilecorrosion Inhibitor- oils conformling to Spes !IL-L-46002(Ord) and MIL-I-2J310(Wep) These oils are,however, specifically preservative oils and notoperational oils, and at uest are not intended for

1 64-3577

continuous nonpreservative operation Moreover, anotherdrawback is the general requirement that the part orvehicle, when ready for a non-use or storage period,must be cleaned and preserved Apart from the cleaningwhich is a most important factor, the preservation processrequires the use of special preservative oils designedfor the purpose, - weapons, hydraulic, automotive, etc.,and these must be in stock or easily available when needed.Then, upon depreservatton, it is further advisable toremove the preservative and install the operational oil.Stocks of both preservative and operational oils arerequired, and In general the preservative oils will notbe the same for hydraulic as fcir weapons or automotiveuses.

If a VCI additive were available which was compatiblewith the operational oil the system. after cleaning,could be charged with operational oil to which the VCIconcentrate was added, and placed in storage in normalfashion. Upon dcpreservation, the dart could be put intouse at once without any need to change the oil. The VCImaterial would volatilize with the heat of use, and theresidue would be operational oil

The use of the VCI concentrate in this mannerrepresents significant savings in storage, labor, andinventory problems, besides reducing the possibilitiesor error thru choice of the wrong preservative. Thesesavings represent a consideraLle advantage, and whereshort use periods alternate wi*l: long idle periods, theaddition of a "dash" of VCI concentrate could in the longrun prevent considerablc damage frcom corrosion.

At the present tume, a number of VCI concentratesin powder, oil, or solvent solution form are available,but no concerted investigations of these materials havebeen undertaken In order to providC ,,ecessary dataconcerning the use of VCI concentrates, it was proposedto Investigate the piacticality and feasibility of addinga VCI concentrate to standard operating lubricant andhydraulic oils to ennacce theii protective characteristics.The results ootained woilu determine the feasibility ofcontinuing this line of investitgation

PROCEDURE AND RESULTS

The following fi,1'is.,eo ciI products were selectedto be bletided with varinus VCI concentrates

The co::c(ntrates which were tested, and thesuggested dilution ratios, are as follows

Code A LIquid 1-3B liquid 1-10C liquid 1-JD solvent --oltJ.on i-5E Powcer 7-I/,2k by weightF Powuer 15.l by weightG Powder 7-1/2% by weightH thix6"ropic gel 7-1/2% by weightI Powder 15% by weight

The volatile corrosion inhibitor concentrates wereadded to ea_. of the base oils in accordance with thesuppliers suggested use ratios. Both the liquid andpowder :oncentra.es were blended with the oils on aweight basis In order to facilitato the .iolution ofthe powders in the base eils. the crystals were finelyground before addition *c the respective oils.

A. EXHAUSTION AND VAPOR P'IAS,1 PROTECTION TESTS

After the addition o. & concentrates to the oils,the mixtures were exhausted as bpecified in par. 4.8.3of Specification MIL-L-460.J2 rhe exhaustion procedureutilized the cvap.cratiozn te-st cell specified in Method351 of Federal Standard No. 791 The protective pro-perties of the exhaus'tod -.iaterials were then establishedutilizing the vapot phase protection test of Spec.MIL-L-46002 A slight modification was made in theequipment used for tois latter t_ t The steel panelsare normall.y nosit;otned in te ,)a-- by means ol a moneiwire support. but due to tl% flex.u,1ity of the supportand the siLe i,...i'ations ol the jar the panels woulcbe partially inraerseu in taiv test oil. The area to beprotected was thus not 'onsrian! To eliminate thisactual contact between il1 and panel, a new fixture wasdevised wherein a curved .•ection of monel wire waspermanently affixed to the test jar lid .ith an epoxy

3 64-3577

resin cement. This modification provided a uniform virporphase environment for all panels, since the entire panelwas now suspended above the test oil in the jar withoutany contact.

These tests were considered to be the most importantof all, and were based on a requirement to achieve resultsaquivaleLnt to a VCI-oil such as MIL-L-46002. Moreover,these tests would provide guidance for continuation of theproject. Results were tabulated in Table I.

Referring to Table I, it is noted that Code Aconcentrate provided satisfactory protection with alloils .ested. The required dilution of 1-3 was not asdesirable as a lower dilution, and the manufacturersupplied another concentrate, Code B, intended for a 1-10dilution ratio. At this ratio 5 of the 8 oil basesfailed. Of these 5, four were satisfactory at a 1-9 ratio,and in the last case, MIL-L-15016 (3065) the lowestsatisfactory ratio was 1-7.

The Code C concentrate was tested at a 1-3 ratio withMIL-L-2104 (Grade 10 and Grade 30) and found to beunsatisfactory. Further testing was discontinued.

The Code D concentrate was tested at a 1-5 ratiowithout satisfactory results, using SAE 10 oils of MIL-L-2134 and MIL-L-15016., When a 1-3 ratio was used, itwas satisfactory with all the oils except MIL-H-6083. Notest was run with 6083 due to incompatibility as reportedlater.

The tests on powder concentrates (Codes E, 2, G,H and I) showed that Code G was unsatisfactory atconcentrations up to 10% while Code E was satisfactoryat 7-1/2% in MIL-L-21C4 oils. Code H failed at 7-1/2%and Code F which required a 15% concentration, alsofailed. The Code I, at 15% concentration, passed thetests with all oils except MIL-H-6083 which was not testeddue to incompatibility.

These results indicated Lhat Codes A, B, D, E and Icould be added to a variety of oils and provide protection.Other factors, however, needed to be considered relativeto the operational and related properties of the criginaloils.

B. SHORT AND LONG TERM COMPATIBILITY TESTS

Short and long term compatibility tests with thevarious base oils were run on some of the concentrates.Storage of the treated oils for short and long terms at

room temperature, approximately 80 0 F., comprised a 5 dayshort term test with daily inspections and a 12 monthlong term test with daily inspections for the first 5 days,followed by monthly checks until completion of the tests.Table II indicates compatibility by observing solubilityafter the short term test.

Of the liquid concentrates, Codes A and B werecompatible with all the base oils, and Codes C and D withall except MIL-H-6083.

In order for a concentrate to be useful it must mixeasily, rapidly, and completely with the base oil. Thiswould, therefore, require that a powder concentrate bealmost instantly soluble. The powder concentrates CodesE, F, G, and I were difficultly soluble in every case.

The powders were easier to blend into the lighteroils than into the heavier bodied oils. Agitation andheat aided in dissolving the powders, but in field usethis may not always be possible, The concentrate wouldnot dissolve completely to provide the desired protection.The recommended 7-1/2% portions of Codes E and G weremost difficult to dissolve in the base oils. Even at3-1/2% the blended solution waG difficult to obtain with-out heat and agitation. The use of heat for this purposehas two major disadvantages (1) it may not be available,and (2) it may prematurely dissipate the volatile inhibitormaterial. These materials (Codes E and G) were compatibleonly with MIL-H-5606 and lormea a gel with MIL-H-6083.

A modification of the short term storage test wasconducted on concentrates marked Code A, Code B, andCode C. Three samples of each concentrate were storedfor two weeks at 160 0 F., 400F., and -65 0 F. At the endof the storage period the samples were examined visuallyfor separation and then added in the proper amount toMIL-L-2104 engine oil. The base inhibitor mixes whichhad been stored at 160 0 F. and 40 0 F. were mixed withGrade 30 oil and were then evaluated for vapor phaseinhibition. The inhibitors stored at -65 0 F. were mixedwiti Grade 10 oil and tested as above. These variationswere made to observe the rapidity and completeness ofmixing, especially with the low temperature concentrate,since some of the desirable attributes of a concentrateare ease and rapidity of mixing.

The results obtained indicated no adverse effectson corrosion protection afforded by Code A and Code Bconcentrates when stored for 2 weeks at temperaturesof 160 0 F., 40 0 F. and -650 F. Code C concentrate providedsatisfactory corrosion protection after storage at 400 F.

but was adversely affected by the temperature extremes of-65 0 F. and 1600 F. The concentrate did not provide corrosionprotection as required in the vapor phase protection testof MIL-L-46002.

A cycling test with Code A and Code B concentrateswas planned with samples stored for one week at 160 0 F.,room temperature, 40vF., and -65 0 F., consecutively. Thevapor phase protection test per paragraph 4.8.2 of Spec.MIL-L-46002 was conducted with MIL-L-2104 engine oil atthe end of each week's test. The original samples were100 ml of concentrate in a sealed container. The testprogressed thru the temperature ranges until the -65 0 F.temperature was reached.

It was shown that Code A and Code B concentratesprovided the desired corrosion protection thru the firstthree temperature test points. The effects of the con-centrate stored at -65 F. were not determined due to themechanical failure of the low temperature environmentaltest chamber after one day's operation.

The long term capatibility tests were originallyintended for a one year tcrm, however, only six monthstesting could be completed on the most promising inhibitors,Code A and Code B. These results are indicated in TableIII.

It is noted that after 6 months storage, the inhibitorswere found to be compatible with only the MIL-H-5606 fluid.A light flocculent type of sedimentation was evident withfive of the base oils: iowever, this was easily redispersed.While it might well form in situ, it is believed that nosignificant effects would ensue since, in service, theequipment upon being activated would redisperse thesediment without adverse effect.

The MIL-L-2104, Grade 30 oil formed a heavy precip-.itate. Although the precipitate would be redispersed inactual use, there is a question concerning its suitability,since the volume of the precipitate denotes some interactionwith the other additives. The acceptability of the sedimen-tation in any case would depend on the continued protectiveproperties of the mixture, as noted in Table IV. The MIL-H-6083 was unsatisfactory as a gelatinous precipitate wasformed.

It was intended to establish the protective propertiesof the stored concentrate-oil mixtures utilizing the vaporphase protection test. Time permitted only the evaluationof the Code A concentrate. These results are indicated inTable IV.

It is noted that the only failure was obtained withtOe MIL-L-2104, Grade 30 oil, where a large amount ofsedimentation had occurred. This was very likely causedby an interaction of inhibitors, however, further studyis required before any definite conclusions can be drawn.

Incomplete tests on the Code B concentrate showedthat similar results would probably be obtained at the1:10 or 1:9 ratios for the respective oils as noted inTable III

C. VISCOSITY TESTS

Since the addition of a VCI concentrate to a baseoil may affect the viscosity characteristics, Codes A, Band D concentrates, w~ilch had passed the exhiaustion anavapor phase tests, were evaluated for viscosity effectsaccording to Method 305 of Federal Standard No. 791.

As indicated in Table V, the addition of Code A andB concentrates caused a significant viscosity change onlyin the case of the MIL-L-15016 (#3065) base oil. Forthe other base oils, any changes evident did not cause theviscosity to deviate significantly from the specificationrequirements.

The Code D concentrate, being a solvent solution,caused noticeable viscosity changes. The presence of thesolvent is a hindrance in many ways and undoubtedly willrequire some remedial action if the material is to begiven any further consideration.

D. FLASH POINT TESTS

Similarly, the flash point was determined for Code A,B and D concentrates in various base oils in accordancewith Method 1103 of Federal Standard 791. These resultsare indicated in Table VI.

It is noted that, with two exceptions, there was asignificant lowering of the flash point by the additionol a concentrate. This was especially true with Code Dconcentrate, a xylene solution. For the Code A and Bconcentrates, the effects seemed to be more a function ofthe inhibitor rather than the carrier oil, which wasprobably an SAE 10 oii.

E. POUR POINT TE>TS

Similarly, the pour point was determined for Code A.B and D concentrates in various base oils in accordancewith Method 201 of Federal Standard No. 791.

It is noted in Table VII that wi.th two exceptions,the MIL-L-2104, Grade 10 oil and the MIL-L-15016, SAE 30oil, all of the pour point values were lowered by theaddition of a concentrate. The most significant changeswere made by the Code D concentrate and this was attri-buted to the influence of the xylene solvent. Loweringof pour points may at times be considered advantageous,especially with tha lower viscosity oil base materialsevaluated.

F. SURVEY OF PROTECTION TESTS ON MIL-L-2104 QUALIFIEDPRODUCTS

Since the original MIL-L-2104 oils, obtained fromlocal stocks, probably represented only one supplier, itwas decided to obtain samples directly from threeadditional qualified suppliers. Vapor phase protectiontests were made with the different oil samples utilizingCode A, B and D concentrates at the previously determinedeffective concentration.

Referring to Table VIII, it is noted that allmixtures satisfactorily passed the exhaustion and vaporphase protection tests.

evaluation.

The treated oils were exhausted before beingevaluated in the vapor phase protection test due to thepossibility that treated oils in actual use may dissipatesome of the volatilc corrosion inhibitor before thedesired protection is needed.

The satisfactory vapor phase protection resultsobtained on the various mixtures utilizing oil con-centrates indicated thi effectiveness of convertingoperating oils to preservative oils The powderconcentrates, however, were unsuitable for thisapplication due to the high concentration of VCI thatmust be employed From the overall results obtained,the powder concentrates warrent no further investigation.

The storage stability test data indccated certainareas of incompatibility. One of these was the MIL-L-2104, Grade 30 and Code A mixture Since thiS lubricantis so widely used, it will be necessary to determinewhiL,, of the additives present in the base oil is thecause of the incompatibility.

Due to tie favorable results obtained in the modifiedshort term storage test, it was decided to extend thistype of test from two weeks to six months. Tests arecurrently in process utilizing the extended storageperiod.

The cycling test was devised to evaluate radicaltemperature changes that may occur in environnentalstorage. Frequently mater,ýal is stored at high,alternately average, or low tcmperatures f(,- varyingtime intervals. A cycling test simulates this typeof storage condition .a5 previously indicated, the lowtemperature phase of t'ie test cycle was not completeddue to mechanical failure of the low temperature testchamber. Satisfactorv results were obtained, however,for the other test temperatAres.

In determining the ieasibility ol using a volatilecorrosion inhibitor, t;he r'sulting viscosity of theblended mixture is important due to tne fact that theaddition of the concentrate may affect the allowableviscosity limits of tne base material. An adverseviscosity change at -65 0 F. might make the mixtureuous-able. It is, therefore, evident that a VCIadditive should only be considered for thc-e lubricantswhich in themselves are better than marginal at lowtemperatures.

15 64-3577

Similar care should also be exercised when consideringflash point and pour point properties. The use of a VCIadditive with materials having values on the low side ofthe requirement, could easily result in mixtures havingvalues considerably below the minimum requirement.

Chemical composition of oils supplied for a usespecification vary between lots and to a greater extentbetween suppliers. The VCI concentrate would of necessitybe utilized with any number of qualified products. It was,therefore, of paramount importance to determine if theconcentrate was compatible with a number of arbitrarilyseiected qualified producers. The concentrates may havebeen uniquely compatible with a single source of supplywhich would present a great supply and logistics problem.MIL-L-2104 being an engine lubricating oil and having alarge number of qualified products was selected for thisevaluation.

The results of this work have reasonably demonstratedthe feasibility of using VCI concentrates in operationallubricants to obtain vapor phase protection comparable tothat of the current MIL-L-46002 VCI oil.

Concentrates are available which will meet thedesired protection requirements and further work in thisarea would probably provide concentrates that will morecompletely satisfy the desired compatibility character-istics and selected physical properties.

On the basis of the data contained in this report,it is recommended that further work be conducted to:

1. Determaine the effects of oxidized oils, or oilswhich have been in storage for a considerable period oftime, on the protection, compatibility, and physicalcharacteristics of the oil-concentrate mixtures,

2. Determine the causative effects of the incom-patibilities which exist between MIL-L-2104 Grade 30 oiland the VCI concentrates during long term storage.

3. Determine if an inhibitor in a solvent-baseconcentrate can be effectively utilized in an oil baseconcentrate.

4. Initiate engine storage tests on the effectiveVCI concentrates to ascertain their value in actualservice.

5. Determine the long term storage characteristicsof uuused, undiluted VCI concentrates.

64-3577 16

6. Determine the most desirable dilution ratioto provide an optimum protection level for use withengine, hydraulic, or general purpose lubricants.

7. Prepare a list of test methods and tentativerequirements to define the product in anticipation ofa Specification.
