Abstract
The oxidation kinetics and mechanism of oxide-scale failure of pure Ni oxidized under external static compressive and tensile loads were studied. The results showed that both types of mechanical loads accelerated the oxidation rate, but the effect was different for the two types. Compressive loading (CL) affected it by improving the plasticity of oxide scales, and tensile loading (TL) affected it by amplifying the compaction of the oxide–metal interface. As for the oxide-scale failure, CL can delayed cracking, TL accelerated brittle failure. The study analyzed the effect of external load on the oxidation kinetics and the failure mechanism of oxide scales.
