Abstract

PURPOSE: To form black Cr plating for decoration with superior wear, corrosion and heat resistances on a substance to be plated by under-plating the surface of the substance with Ni and subjecting it to bright Cr plating, black Cr plating and bright Cr plating.
CONSTITUTION: The surface of a substance to be plated is cleaned, activated, and underplated with Ni, Cu-Ni, Cu-Ni-Cr or Ni-Cr in about 20μm thickness. It is then subjected to bright Cr plating in 0.1W0.3μm thickness, black Cr plating in 2μm thickness and bright Cr plating in 0.001W1.0μm thickness in succession. Thus, a black Cr plated substance for decoration with superior wear, corrosion and heat resistances is obtd. It is hardly scratched and has lustrous superior appearance.
