Abstract
An aluminized NiCrAlYSi coating and Pt modified aluminized NiCrAlYSi coating were prepared on a Ni-based superalloy. Isothermal and cyclic oxidation behaviour of both coatings were investigated. The Pt modified aluminized NiCrAlYSi coating showed an enhanced oxidation resistance due to the presence of Pt decreasing the oxidation rate and improving the adherence of alumina scale. The addition of Pt in aluminized NiCrAlYSi coating inhibited the phase transformation from β to γâ². Besides, the surface rumpling of Pt modified aluminized NiCrAlYSi coating was suppressed as compared to the aluminized NiCrAlYSi coating.
