Technical Data Sheet

Description of Titanium Nitride Powder

Titanium nitride (TiN) (sometimes known as Tinite or TiNite) is an extremely hard ceramic material, often used as a coating on titanium alloy, steel, carbide, and aluminum 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, and as a non-toxic exterior for medical implants.

Synonyms

Titanium nitride powder, TiN, Ti2N, NTi, Tinite, TiNite, TiNi, azanylidynetitanium, CAS# 25583-20-4

Typical Applications of Titanium Nitride Powder

The most common use for TiN coating is for edge retention and corrosion resistance on machine tooling, such as drill bits and milling cutters, often improving their lifetime by a factor of three or more.

Because of TiN's metallic gold color, it is used to coat costume jewelry and automotive trim for decorative purposes. TiN is also widely used as a top-layer coating, usually with nickel (Ni) or chromium (Cr) plated substrates, on consumer plumbing fixtures and door hardware. TiN is non-toxic, meets FDA guidelines and has seen use in medical devices such as scalpel blades and orthopedic bone saw blades where sharpness and edge retention are important [5] and bio-implants, as well as aerospace and military applications.

Such coatings have also been used in implanted prostheses (especially hip replacement implants). Such films are usually applied by either reactive growth (for example, annealing a piece of titanium in nitrogen) or physical vapor deposition (PVD), with a depth of about 3 micrometers. Its high Young's modulus (600 gigapascals)[6] relative to titanium alloys (100 GPa) means that thick coatings tend to flake away, making them much less durable than thin ones.

As a coating, it is also used to protect the sliding surfaces of suspension forks of bicycles and motorcycles as well as the shock shafts of radio controlled cars.

Though less visible, thin films of TiN are also used in the semiconductor industry. In copper-based chips, such films find use as a conductive barrier between a silicon device and the metal contacts used to operate it. While the film blocks diffusion of metal into the silicon, it is conductive enough (30–70 µO•cm) to allow a good electrical connection. In this context, TiN is classified as a "barrier metal", even though it is clearly a ceramic from the perspective of chemistry or mechanical behavior.
