Prelucrare prin eroziune chimic

Principalele metode industriale de prelucrare prin eroziune chimic

Prelucrare anodomecanic

Prelucrare prin eroziune chimico-electric

Prelucrare cu ultrasunete Prelucrare cu ajutorul oscilaiilor ultrasonore

Prelucrare cu ultrasunete

Prelucrarea prin procedeu chimic

Figura 2 (a) Panou exterior de rachet prelucrat prin eroziune chimic pentru mbuntirea raportului greutate-rigiditate. (b) Reducerea greutii vehiculelor spaiale prin prelucrarea aliajelor de aluminiu prin metoda eroziunii chimice. Panourile sunt prelucrate chimic dup ce, n prealabil, au fost obinute prin alte procedee cum ar fi laminarea. Modelul nervurilor de pe panou se poate modifica la costuri minime pentru alte procedee de eroziune chimic.Manufacturing, Engineering & Technology, Fifth Edition, by Serope Kalpakjian and Steven R.
