en موتور احتراق داخلی Internal Combustion Engines (ICE, ...) پژوهشي Research In the present paper, a complete literatures review of thermal barrier coating applications in diesel engines is performed to select a proper type and to find coating effects. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of engine components. Usually there are several beneficial influences by applying ceramic layers on the combustion chamber, including the piston, the cylinder head, the cylinder block, intake and exhaust valves by using a plasma thermal spray method. Several disadvantages such as producing nitrogen oxides also exist when a coating system is used. In this article, all effects, advantages and disadvantages of thermal barrier coatings are investigated based on presented articles. diesel engine, thermal barrier coating, plasma spray, fuel consumption, fatigue lifetime 305 317 http://ase.iust.ac.ir/browse.php?a_code=A-10-63-33&slc_lang=en&sid=1 Azadi farrahi@sharif.edu 18003194753284600793 18003194753284600793 Yes Baloo 18003194753284600794 18003194753284600794 No Farrahi 18003194753284600795 18003194753284600795 No Mirsalim 18003194753284600796 18003194753284600796 No
