Abstract

Abstract

Surface treatment to the Ni₃Al intermetallic compound was conducted by high energy density plasma and nanometer micro-crystalline layers were developed on the alloy surface.Formation of protective Al₂O₃, scales on the alloy surface was promoted by increasing the nucleaton sites and enhancing the outward ditheion of Al in the micro-crystalline structure. The fast growing phase NiO was eliminated in the oxide scales.
