The properties of machine elements must be suitable for their working conditions because they may be subjected to heavy working conditions such as resistant to fatique, wear, corrosion and high temperature during the service life. Their microstructure and surface properties have to support the requirements for these conditions. For these reasons, the microstructure and surface properties of the components to be worked at high temperature should be improved by suitable treatment methods such as PVD coating, surface alloying or coating and thermochemical heat treatments, etc.
