Abstract

PURPOSE: To make titled constitution of gold plating low in cost and good in corrosion resistance by carrying out Au-Ag-Cd alloy plating between a blank and gold alloy finish plating applied on the outside surface.
CONSTITUTION: In this constitution of gold plating for external finishing parts for timepiece, Au-Ag-Cd alloy plating is carried out on the surface of a blank using a German Silver or brass material, and alloy plating of Au-Ni, Au-Co, Au-Cu etc. is carried out as finish plating thereon. In this case, the Au-Ag-Cd alloy plating consists, by weight %, of 40W55% Ag, 5W15% Cd and the balance gold and unavoidable impurities and its thickness is kept within a 0.25W5μ range.
