摘要：

The oxidation of NiAl at 950-degrees-C was studied for samples having the three different orientations (111), (100), and (110) both undoped and superficially doped with Pt. Differences in oxidation rates and scale morphology were observed during the first 100 h of scale growth depending on orientation and Pt doping; these are caused by differences in nucleation and the THETA- to alpha-Al2O3 transformation. No distinct, positive 'precious element' effect was exerted by the presence of Pt; a retardation of the THETA - to alpha-transformation and a decrease of metal-oxide coherence were noted however.
