Gold Titanium Nitride (TiN) Coating

Often used in a number of decorative applications, Titanium Nitride is a very attractive, bright gold ceramic coating applied to metallic surfaces by the physical vapour deposition (PVD) process. The coating has high hardness and low friction combined with moderate resistance to oxidisation. Tecvac produce TiN coatings using a process of electron beam evaporation under vacuum at a work piece temperature of about 480°C. This method results in coatings which are very smooth and require no post coating finishing. TiN coatings are widely used to improve the life and performance of cutting and press tools, where a cost effective reduction in tool wear is required. It can also be applied as a wear indicator.
