Tiaano Platinised Titanium Anodes are most suitable for electro plating (Metal Finishing). The behaviour of platinized titanium ‘slave’ or ‘auxiliary’ anodes in electroplating is described, with particular reference to use in the plating of gold, rhodium, nickel, copper, tin and chromium. Preceding this survey some characteristics of commercially available platinized titanium are considered, including method of preparation, overvoltage, composition and platinum thickness. The results of accelerated laboratory tests to define limiting conditions of use are given, and durability is contrasted with that of alternative experimental noble-metal-coated refractory metals. Degradation of anode surfaces encountered in some practical applications is attributed to platinum dissolution resulting from reaction with particular organic additives, but in some circumstances an undermining of the coating as a result of superficial dissolution of the titanium may occur.

Platinised titanium anodes were the first coated electrodes to be marketed, and in many applications they have been displaced by dimensionally stable oxide coatings that have been highly optimised for the particular electrolyte. However, there remains a market for anodes which can be used in relatively small scale processes and this could be met by high performance, platinised titanium anodes. Indeed, the number of such applications in electrosynthesis and environmental processing is expanding. It may be timely, therefore, to re-examine the manufacture and performance of platinised titanium anodes and to consider using platinum alloys for nonspecific applications; for example, platinum/iridium coatings on titanium are known to have superior properties in some applications.
