Vapour-deposited hard coating like TiN, ZrN and a great number of ternary or multicomponent compounds of the transition show a variety of colours out of which the golden TiN is the most well-known tint. The use of such coatings for decorative purposes combines their decorative properties with their excellent wear resistance and good corrosion resistance. In the present paper first the colours and their dependence on composition and process parameters are discussed followed by information on the corrosion behaviour of coating/substrate systems and their testing methods. Finally, examples are given for the application of decorative hard coatings and specific coating sequences for improvement of the corrosion resistance if less noble substrate materials have to be coated.
