Abstract

PURPOSE: To enhance the wear and heat resistances of black Cr plating by plating a substance with Ni (alloy) to form a ground and further plating it with black Cr and bright Cr in a specified thickness in succession.
CONSTITUTION: A substance to be plated such as external parts for a car is plated with Ni, Cu-Ni, Cu-Ni-Cr, Ni-Cr or the like in a plurality of layers to form a ground. It is then plated with prescribed black Cr and further plated with bright Cr in 0.001W0.1μm thickness. This black Cr plating has superior wear resistance, less unevenness, stability, a low degree of discoloration and superior heat resistance.
