Nano Coatings on Cylinder Liner

In recent years research and development on metal matrix composite coatings (MMCs) have been gaining importance. These composite coatings possess enhanced properties such as wear corrosion and oxidation resistance dispersion hardening or self-lubrication relative to pure metal so that they can protect the metal substrates more effectively against severe environments during operation. MMCs find applications as wear resistant coatings self-lubricating films and thermal barrier coatings. However these properties depend on the contributions from the distributed and matrix phases of a composite coating. One of the continuing goals of the nano composite coatings is the production of coatings with enhanced properties such as higher micro hardness corrosion resistance and wears resistance.
