摘要
PROBLEM TO BE SOLVED: To provide an electrolytic processing method for hard metal, capable of preventing Co elution on a part where it contacts an electrolyte during electrolytic processing, and preventing Co elution on a processed surface, in Co ion addition to the electrolyte.;SOLUTION: When the hard metal is subjected to electrolytic processing, as an electrolytic processing solution, a solution mainly formed of salt water or nitric acid soda solution, is used. Cobalt ion is added to the electrolytic processing solution, and during electrolytic processing, flushing is performed so that the electrolyte is circulated between an electrode and workpiece. A charge amount of current in which the electrode is a negative electrode is larger than a charge amount of current in which the electrode is a positive electrode.;COPYRIGHT: (C)2016,JPO&INPIT
