The good corrosion resistance of titanium and particularly the ability of the metal to passivate anodically in acidic environments is resulting in increasing use of this metal in metal finishing processes. The anodic passivation properties of titanium are described by reference to polarization data, and the conditions under which the passive film may break down are defined. The practical use of titanium is illustrated by reference to employment of the metal in anodizing jigs, in heating and cooling coils, as anode baskets and in galvanizing baths. The ability of the combination of titanium coated with thin films of noble metals to conduct anodically to electrolytes is discussed, and the application of these principles to inert anodes in plating baths is described.
