Abstract
Coatings are materials deposited on surfaces to enhance a specific set of performance attributes, i.e., wear resistance, erosion resistance, corrosion resistance, friction reduction, etc. Since wear, corrosion, and friction phenomenon are restricted on the surface, deposition of a coating provides a great flexibility in imparting properties which could be significantly different from the parent material. There are wide varieties of materials available for deposition and the choice of a material depends on the application, compatibility with the base material, and the deposition process. This chapter first reviewed lubrication regimes in critical tribological contacts (cam and tappet in valvetrain, piston and piston rings and cylinder bore, piston pins, and bearings) in an engine to justify where coatings could improve friction reduction and durability. Then, described coatings being used/explored in each of these applications followed by an outlook of coating technologies in future automotive engines.
