PLATING TREATMENT METHOD FOR PREVENTING HYDROGEN BRITTLENESS

摘要

PROBLEM TO BE SOLVED: To provide a treatment method for preventing the occurrence of brittleness by occluding the hydrogen generated in pretreatment and plating in subjecting high tensile strength steel, etc., to plating. SOLUTION: The plating treatment method for preventing hydrogen brittleness comprises using a PR electrolysis (forward and backward AC electrolysis) as the electrolyte treatment of the pretreatment in the plating treatment method for the high tensile strength steel, etc. COPYRIGHT: (C)2003,JPO
