Abstract

PURPOSE: To obtain gold plated external parts having corrosion resistance and abrasion resistance as well as high grade feel for external parts for watches by applying the Au-Cu-Cd plating of specific composition and specific thickness between underlying plating and gold or gold alloy finish plating.
CONSTITUTION: First, Au-Ag-base alloy plating is applied as underlying plating on the surface of a blank material, then the Au-Cu-Zn plating comprising 10W25 Cu in wt%, 2W4 Cd, and Au and unavoidable impurities for the remainder is applied thereon. The thickness of the plating layer is kept at 0.25W5μ. After this, Au-Ni- base alloy plating is applied as finish plating.
