Titanium Nitride (TiN)

Titanium Nitride is a 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.

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.

The coating has a very attractive bright gold colour, and this distinctive feature has resulted in TiN also being used in a number of decorative applications.
