A review of thermal barrier coating effects on diesel engine performance and components lifetime

In the present paper, a complete literatures review of thermal barrier coating applications in diesel enginesis performed to select a proper type and to find coating effects. The coating system has effects on the fuelconsumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of enginecomponents. Usually there are several beneficial influences by applying ceramic layers on the combustionchamber, including the piston, the cylinder head, the cylinder block, intake and exhaust valves by using aplasma thermal spray method. Several disadvantages such as producing nitrogen oxides also exist when acoating system is used. In this article, all effects, advantages and disadvantages of thermal barrier coatingsare investigated based on presented articles.
