Abstract

The high temperature oxidation behavior of low pressure plasma sprayed (LPPS) NiCrAlY coating on nickel - base superalloy was studied at 1050°C in a flow of O2, mixtures of O2 and 5% H2O under atmospheric pressure. Oxide formed on the surface of LPPS NiCrAlY coating after oxidation at 1050°C in pure O2 consisted of Al2O3, whereas oxide formed on the surface of LPPS NiCrAlY coating after oxidation at 1050°C in a mixture of O2 and 5% H2O is composed of Al2O3,Cr2O3 and NiO. The effect of water vapor on the characteristics of the oxide scale formed is attributed to the increase in Ni cation transport.
