| 摘 要： | The oxidations of low pressure plasma sprayed (LPPS) NiCrAlY coating on nickel base superalloy were studied at 1050℃ in flows of O2, and mixture of O2 and 5%H2O under atmospheric pressure. Oxide formed on the surface of LPPS NiCrAlY coating after oxidation at 1050℃ in pure O2 consisted of NiCr2O4, whereas oxide formed on the surface of LPPS NiCrAlY coating after oxidation at 1050℃ in a mixture of O2 and 5%H2O is mainly composed of NiO. The effect of water vapor on the characteristics of the oxide scale is attributed to the increase in Ni cation transport.
