Role of laser radiation in activating anodic dissolution under electrochemical machining of metals and alloys

Role of laser radiation in activating anodic dissolution under electrochemical machining of metals and alloys

The specific features of electrochemical dissolution of the 12X18H9T stainless steel, the OT-4 titanium alloy and the BK8 hard alloy in the sodium nitrate water solution exposed to 1.06 micrometer wavelength laser radiation were considered. It is found that depassivation of the anode surface is the...
