METHOD OF FORMING CERMET COATING HAVING DENSE SURFACE LAYER, AND CERMET COATING COVER MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method of forming, on a surface of a base material, a cermet coating having a dense surface layer excelling in corrosion resistance and wear resistance, and a cermet coating cover member obtained by the method.;SOLUTION: The method is used for immersing a non-conductive ceramic thermal spray coating formed on a surface of a conductive base material in an electrogalvanizing liquid, forming a cermet coating filled with plating deposition zinc by filling the plating deposition zinc in pores of the ceramic thermal spray coating by performing an electrogalvanizing treatment, and then re-melting the coating surface to produce a dense surface layer by performing a high-energy irradiation treatment. This coating cover member is thus obtained.;COPYRIGHT: (C)2012,JPO&INPIT
