ANTI-DEFACEMENT INGREDIENTS

摘要

An abrasion resistant mechanical member having a composite Ni plating layer on the surface of the member, which is formed by electrolysis by the use of an Ni electroplating bath. To achieve the intended purpose, the Ni electroplating bath is added to tensile stress accelerating agent and compression stress accelerating agent in addition to ceramic powder. The electrodeposited member is subjected to reverse electrolysis for forming a porous portion in the composite Ni electroplating layer which exhibits an excellent oil retention together with abrasion resistance.
