Coating is a layer of a substance applied to the substrate surface.
Coating is also a process of applying a layer to the substrate surface.
Coating material is different from the substrate material and it permits achieving special surface properties of the part without changing its bulk properties.
Coatings may improve the following surface properties:
TiN, TiAlN, TiCN, NiN coatings for cutting tools.
Metal coating of steel (Zn, Ni, Cr).
Ceramic coating for high temperature oxidation protection.
Engine bearings electroplated with Pb-Sn-Cu, or sputter coated with Al-Sn.
Diamond like coatings for tools, dies, valves.
Carbon and MoS2 coatings for camshafts, pistons, cylinder-head studs, conveyor chains.
PTFE (Teflon®) anti-stick coatings for food industry, medical devices, electrical equipment.
TiN gold-like coatings for jewelry, eye glass frames, watches, pens.
Black oxide coating of bearings, gears, firearms, journals.
The following technologies are used for applying coatings on metals:
