Blue PVD coating means blue color in PVD coating.In thermal evaporation, blue color is by oil paint, also called pigment. In multi arc and magnetron sputtering, titanium target and oxygen(O2) gas will coat blue color by specific recipe.Blue PVD coating color is popular in plastic toy, watch, motorcy

Black PVD coating means black color in PVD coating. In multi arc, usually, black color can be coated by titanium target + C2H2 gas, but it is normal black. To reach darker black color, we need to choose chrome or CrSi target. What’s more, mid frequency(MF) magnetron sputtering target is the best cho

This “gold” can be real gold(Au) or imitated gold(titanium gold, zirconium gold or gold pigment).As for real gold, we may use DC plane magnetron sputtering target, which is popular in jewelry.On the other hand, titanium gold and zirconium gold can be reached by cathodic arc and magnetron sputtering.
