Effect of degassing electrolyte on polarisation curve shape with the aim to apply knowledge to electrochemical machining

Abstract

Copyright © 2014 Future Technology Press and the authors. Electrochemical machining is a manufacturing process which relies on the anodic dissolution of the work piece. The accuracy of the hole created is dependent on a number of factors including the applied potential. A higher applied potential creates a larger overcut and therefore decreased accuracy. Early indications from polarisation curves suggest that removing dissolved oxygen from the solution can somewhat prevent passivation of the work piece surface allowing a lower machining potential to be used which should improve machining accuracy.
