Titanium Nitride
Titanium nitride (TiN) is a hard ceramic material with a metallic luster. It is composed of titanium and nitrogen and is known for its high hardness, wear resistance, and chemical stability. TiN is often used as a coating for various materials, including metal and ceramic surfaces, to enhance their durability and performance.
The following table provides a comprehensive list of titanium nitride properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
