What arc targets /cathodes can we supply for decorative coating?

Since the mid 1990s decorative PVD coatings have been established as the high quality surface finish for watches, sanitary and door hardware with many manufacturers marketing coated products with long time guarantees on their appearance.it offers a longer lifetime, metallic colors, scratch protection and is environmentally friendly.
Comparing to traditional electroplated coatings, PVD coating has superior hardness and wear resistance, do not discolour or tarnish, have reasonably high corrosion resistance and do not suffer under UV radiation and so for example PVD Coating wheels and PVD coated watches, in particular DLC coated black PVD watches have proved popular.

PVD Coating Colours
PVD coatings can be deposited with a wide colour range. 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.

Xinkang has been supplying various arc targets for manufacturers of watch, sanitary ware, car mirrors, etc, which are suitable for most of magnetron sputtering machines and ion plating machines. The sputtering targets we can supply for decorative coating includes the follows materials:
