Abstract:The cyclic oxidation behavior of IN738 alloy and it s nanocrystalline coating has been studied. The results indicated that the cycli c oxidation resistance of nanocrystalline coating was better than that of IN738 alloy at 950℃.The oxidation of nanocrystalline coating formed a double externa l oxide scale without internal oxide or nitride. The scale consisted of an outer part of Cr2O3 and spinel and an inner part of a continuous Al2O3 scale, which offered good adhesive and protectiveness. Thus,the cyclic oxidation resi stance of the coated IN738 alloy was significantly improved. 
