Dear all,Currently there are many products, ie. watches, that advertise as PVD coat.
These products have black colour.
Theoretically, there are many coatings that have black colour, ie. SiC, TiAlCN, TiCN etc.
But .... which is the most popular? and Why?
Also .... which kind of coating system is the most suitable for these film. (Magnetron sputterring, Cathodic Arc, E-beam, Hollow Cathode, etc.)
How about the growth of demand on black colour coating for decorative purpose.
Thank you very much.
