The effect of grain refinement on the oxidation and phase transformation of alumina scale on Ni2Al3 coating

An ultrafine-grained (UFG) and coarse-grained (CG) Ni2Al3 coating were prepared by aluminizing pure nickel substrate with and without nanocrystalline Ni film using an aluminization pack cementation process at 620 °C for 5 h. The oxidation kinetics and cyclic oxidation result show that the UFG-Ni2Al3...
