Metals used as target material in decorative PVD processes are zirconium, titanium, chromium, titanium-aluminum alloys and niobium. Ceramic coatings are deposited to increase the hardness of the coating. This is achieved by introducing reactive gases during the deposition process. The most widely used reactive gases for decorative coatings are nitrogen and methane or acetylene to produce metal-nitride, metal-carbide, metal-carbonitride and diamond like carbon DLC coatings. Also oxygen can be used to produce oxides, oxinitrides, etc. The decorative coatings are produced in a certain colour range, depending on the metal-to-gas ratio in the coating and the structure of the coating. Both of these factors can be altered by changing the deposition parameters.
