Effectiveness of Materials as Thermal Barrier Coating for I.C. Engines – A Review

Abstract

 This review article analyses the research articles submitted for past one decade in various combinations of materials in thermal barrier coated engines. Thermal insulation materials have a major impact on the efficiency of automotive engines. More efficiency is expected to increase the operating temperature. This paper examines the different aspects and applications of the thermal insulation materials. The system has an impact on fuel consumption, fuel efficiency, and pollution content and fatigue life of an engine components. The thermal insulationon the top layer of the piston decreases thermal conductivity that increases the unburned oxidation of fuel, decreasing in thermal tension of the engines by exposing the metal substrates at low peak temperature. The article discusses the performance, merits and de-merits of TBC.
