Effect of alloying elements and ceramic coating on the surface temperature of an aluminum piston in a diesel engine
(HINDAWI LTD, 2022) Vengatesan, S.; Yadav, Paras; Varuvel, Edwin Geo
The engine piston is subjected to very high temperature during the combustion process, and it is very difficult to control the stability of the geometry at elevated temperature. The stability of the engine piston was analysed by finite element method with steady-state conditions for three different types of approach to control it, where the influence of the alloying element of aluminum piston, influence of surface coating, and its impact on the thickness variation followed by the influence of holes on the coating surface have been analysed in detail. It is observed that the coating with holes shows good agreement with requirement compared to the influence of the alloying element and coated piston. The conduction mode of heat transfer is controlled, and also, the heat transfer to the adjacent components is facilitated by holes on the coated piston.
