What is a Titanium nitride (TiN)?

Titanium nitride (TiN) is an extremely hard, wear-resistant compound composed of titanium and nitrogen. It is widely used as a surface coating for metal tools, cutting equipment, and decorative applications. TiN's golden, metallic luster is not only aesthetically appealing but also adds durability and resistance to abrasion. Commonly applied using physical vapor deposition (PVD) methods, TiN coatings enhance the lifespan and performance of industrial tools. Additionally, its biocompatibility makes it suitable for use in medical implants and surgical instruments. In the electronics industry, TiN is used as a conductive layer or diffusion barrier in semiconductor manufacturing. It also offers excellent resistance to oxidation and corrosion, maintaining stability in high-temperature and harsh environments. The strong adhesion between the TiN layer and the substrate further increases its value in precision applications. Thanks to its combination of functional and decorative properties, titanium nitride continues to find applications in sectors ranging from aerospace and manufacturing to healthcare and consumer electronics.
