Abstract

A dry ionic process for gold plating substrate articles 5 comprises suspending an article from a holder 2 in a vacuum chamber 1 above a heated bath of a gold-based plating alloy 3 and applying a voltage from an electrical supply 4 between the articles 5 and the bath 3 to deposit vapour of the alloy. The invention lies in the use in the bath of a gold- based alloy containing at least one of the following alloying metals:- chromium, iron, cobalt, nickel, palladium and copper, the content of the or each alloying metal being, for the chromium, iron, cobalt and nickel in the range of from 1% to 10% by weight, and for the palladium and copper in the range of from 0.5 to 20% by weight and the balance of the alloy except for impurities being gold, and heating the alloy in the bath to a temperature in the range of from 1000 DEG to 1500 DEG C. By the use of an alloy as described above, the process can be carried out using a single alloy bath instead of using two or more different baths from which single metals are vaporized simultaneously and in this way various difficulties previously encountered are avoided. Despite the simplification of the process, the plating obtained is satisfactory in all respects including the control of the colour tone of the plated surface and the corrosion resistance and adhesion strength of the plating. <IMAGE>
