Titanium Nitride (TiN) is the most common vacuum deposited hard coating in use today. It is an extremely hard, thin film coating that is applied mostly to precision metal parts. It has an excellent combination of performance properties, attractive appearance, and safety.

BENEFITS OF TITANIUM NITRIDE COATINGS

FEATURES OF TIN COATINGS

Process: PVD Vacuum Deposited Coating.
Appearance: Metallic Gold
Thickness: Ranges from 0.25 to 12 microns. Typical applications are 1 to 5 microns
Uniformity: Coating conforms uniformly to the substrate. No buildup occurs on corners (unlike plating operations). Coating "throws" well into features. In deep holes, coating tapers off from 1 to 7 diameters of depth.
Hardness: Equivalent to approximately 85 Rc. Harder than hard chrome or carbide material.
Adhesion: The coating forms a metallurgical bond to the substrate that will not flake, blister, chip or peel. In fact, the coating is actually implanted slightly into the surface layer of the substrate.
Coefficient of Friction: TiN generally provides low friction against steels, carbides, TiN, ceramics, platings, etc..
Non-stick: TiN is an excellent non-stick surface against most other materials.
Toxicity: Non-toxic. Meets FDA guidelines and has been approved for use in numerous medical/surgical devices, including implants. Meets requirements of FDA and USDA for food contact.
Temperature Resistance: Begins to oxidize at 600 C. (1100 F.) in air
Melting Point: 2930 C.
Deposition Temperature: Ranges from 200 to 450 C. Standard process is 400 C. and provides the toughest coating.
Chemical Resistance: Highly inert to acids, bases, solvents, caustic, etc.
