Abstract
PURPOSE: To make titled constitution of gold plating low in cost and good in corrosion resistance by carrying out Au-Ag-Zn alloy plating between a blank and gold alloy finish plating carried out on the outside surface.
CONSTITUTION: In this constitution of gold plating for external finishing parts for timepiece, Au-Ag-Zn 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, Au-Sn, etc. is carried out as finish plating theren. In this case, the Au-A Ag-Zn alloy consists, by weight %, of 40W55% Ag, 5W15% Zn and the balance gold and unavoidable impurities, and its thickness is kept within a 0.25W5μ range. By the employment of this Au-Ag-Zn alloy plating, the gold plated external finishing parts for timepieces is made low in cost and good in quality.
