Diamond-Like Carbon (DLC) coating is a single layer of hard carbon, deposited using highly specialised coating methods. DLC coatings are used to modify the surfaces of materials and improve the tribological and other properties. DLC coatings have many advantages because of their low cost and their abilities to provide diamond-like properties to different surfaces. DLC coatings can be deposited on nearly all metals, metal alloys, and also on non-metals such as silicon, glass, ceramics, plastics, etc. DLC can be deposited at low (<200C) substrate temperature.
Desirable properties include:
good wear resistance
low friction coefficient
thermal stability up to ∼ 400 oC.
Markets and applications DLCs are used in include:
