英文摘要	Corrosion behavior of the binary Ni-xAl alloys (x = 6, 10, and 15 at.%) is comparatively studied in pure oxygen with and without a ZnCl2-KCl melt deposit at 700 degrees C. The oxidation of all alloys in oxygen atmosphere is strongly accelerated by ZnCl2-KCl deposits, with the formation of porous oxide scales and internal attack of the matrix induced by chlorine. The corrosion resistance of Ni-Al alloys under these present corrosion conditions is improved with increasing aluminum content of alloys, which is ascribed to the formation of alumina in the inner layer of corrosion products. The effect of aluminum is attributed to the increasing of the Al2O3 content in the oxide scales, which may act as barrier to prevent the rapid migration of the reactants through the oxides film layer. A mechanism accounting for the accelerated corrosion of Ni-Al alloys beneath ZnCl2-KCl deposits is regarded as a result of the combination of electrochemical reactions and active oxidation under mixed chlorides deposits.
