Abstract

PURPOSE: To form a gold plating layer of the contents of gold increasing gradually from the root part toward the surface layer part by changing current density continuously in the same plating bath in carrying out gold plating to decorative articles or the like.
CONSTITUTION: An underlying plating layer of Cu, Ni, etc. is formed to 1W5μ thicknesses on the surface of a blank material 3 to be plated. Next, the material is immersed in a plating bath of gold alloy such as Au-Ni alloy or Au-Co alloy and current density is changed continuously or stepwise, whereby a gold plating layer 1 of the contents of gold increased from 10W15 karats to 10W20 karats from the root part in contact with the layer 2 toward the surface layer is formed.
