Titanium nitride (TiN) coatings are widely used due to their excellent durability, heat resistance, and wear protection. The primary uses include：
1.Tool Protection and Performance: TiN coatings are commonly used on cutting tools, drills, taps and molding tools. During machining, TiN coatings extend tool life, increase productivity, reduce friction and improve surface quality. Tools coated with TiN last up to seven times longer than uncoated tools.
2.Medical applications: TiN coatings are used in medical implants such as hip joints, heart valve replacements and dental prostheses.
3.Decorative and Functional Uses: TiN's gold-like appearance can be used to decorate jewelry and automotive trim.
4.Industrial and electrical applications: TiN is used as a barrier layer in microchips and electronics.
