Low administering the electric plating treatment to the production mannered null metal basic material surface

摘要

PROBLEM TO BE SOLVED: To provide a metal plate in which hard chromium plating is applied to the surface of a metal base material, and further, the hard chromium plated layer formed by the hard chromium plating is subjected to particulate shot peening, so as to reduce or extinguish fine cracks in the hard chromium plated layer, thus the low friction properties and wear resistance of the surface in the metal base material are further improved though the same has not been realized by the original hard chromium plating, and to provide a method for producing the same.;SOLUTION: Hard chromium plating is applied to the surface of a metal base material 1 to form a hard chromium plated layer 2, and further, the hard chromium plated layer 2 is subjected to particulate shot peening treatment, thus fine cracks 3 on the surface of the metal base material 1 are reduced or extinguished.;COPYRIGHT: (C)2007,JPO&INPIT
