reportTechnologies to produce and apply tribological nano-coatings
1.3.1 Definition

In this sub-sector of the transport report tribological coatings and relevant processing technologies that are suitable for applying tribological coatings on parts which are used in automotive and aeronautics industry are assessed.

Tribological coatings are coatings that are applied to the surface of a component in order to control its friction and wear. They can be single phase, multi-phase or composite coatings consisting of materials such as carbides (e.g. WC, TiC, SiC), nitrides (e.g. TiN, CrN), metals (e.g. W, Ti, Mo) or ceramics (e.g. Al₂O₃, Cr₂O₃). These coatings can be applied to all kinds of substrates (tough most of the substrates to be protected are usually metallic and/or ceramic). These coatings can be processed mainly by two different methods, thermal spraying and vapour deposition processes.

Details of these tribological coatings and their processing methods especially for automotive and aeronautics industries can be found in the following chapters.
