Abstract Nickel based superalloy, Inconel 718, is one of the main candidates for high temperature applications such as air craft, land base and marine turbines. This technical paper deals with high temperature erosion behaviour and its mechanism of Al2O3–40TiO2 (A40T) coating on Inconel 718 alloy. Al2O3–40TiO2 coatings through plasma spray method were made on Inconel 718. The erosion behaviour of the A40T coating was studied using hot air jet erosion experiments at 800°C with varying parameters… Expand
