Abstract

Titanium nitride (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.

TiN coating is for edge retention and corrosion resistance on machine tooling
The TiN coating is used for machining (carbon, alloy, and stainless steels, cast irons, and aluminum alloys) and protecting dies, moulds, punches, and a range of metal stamping and forming tools.
It is also used for decorative components and as a direct gold plating replacement as it approximately the same colour.
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.
As a coating it is also used to protect the sliding surfaces of suspension forks of bicycles and motorcycles.
