Ceramic based thermal barrier coatings are considered as candidate materials for coating of engineering components subjected to elevated temperatures in operating conditions. In this study efforts are taken to gather the information regarding the TBC materials, Bond coat materials, coating methods and effect of TBC materials on engine performance and emission. Ceramics, in contrast to metals are often more resistance to oxidation, corrosion, wear as well as being better thermal insulator. Many researchers have carried out large number of studies on LHRE concept. In case of LHR engine almost all theoretical studies predict improved performance but many experimental studies shows different picture. It is concluded that much more research is needed to overcome the practical problems before LHR engines can be put into production.
