ABSTRACT:
A process for electrochemically stripping tungsten carbide from a titanium or titanium alloy substrate in an electrolytic cell. A tungsten carbide coated titanium or titanium alloy workpiece is immersed in an aqueous solution of chromic acid and made the anode in the electrolytic cell. An inert metallic cathode is provided. Direct current is imposed on the cell to effect anodic stripping of the titanium or titanium alloy substrate.
