Abstract
The oxidation behavior in air of a platinum containing nickel based superalloy (RJM2012) is compared with that of a similar alloy (IN792+Hf) without platinum. The distinct improvement in the oxidation resistance of the platinum containing alloy at high temperatures (1100°C) is explained in terms of the oxide morphologies and oxidation kinetics. In particular, it appears that platinum has a small but significant effect on the diffusion of other species in the alloy, and a model is presented to account for the complex sequence of oxide development, which culminates in the formation of a protective alumina scale.
