Titanium nitride (TiN) (sometimes known as “Tinite” or “TiNite” or “TiN”) is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Applied as a thin coating, TiN is used to harden and protect cutting and sliding surfaces, for decorative purposes (due to its gold appearance), and as a non-toxic exterior for medical implants. In most applications a coating of less than 5 micrometres (0.00020 in) is applied.
The titanium nitride coating TiN was introduced by India Carbide and it remains a proven and versatile standard coating. It provides effective protection against abrasive and adhesive wear. It is often applied for its decorative effect or as a wear indicator.
Coating Properties:
- Coating Material : TiN
- Hardness (HV 0.05) : 2,400
- Coating Temperature (°F) : 930
- Friction Coefficient on Steel (dry) : 0.5
- Thickness (µm) : 1.5 - 3
- Oxidation Resistance (°F) : 1,100

Recommended applications of TiN Coating:
- steel cutting
- punching and forming (when working low-hardness materials)
- molds for the injection molding of plastics
- plungers of diesel injection pumps
- medical instruments
