Abstract

Y-Ce-Co-modified aluminide coating on nickel base superalloys was prepared by pack cementation method. The microstructure and hot corrosion behavior of the coating were investigated. The results indicate that Y-Ce-Co-modified aluminide coating has a mass gain of only 0.32mg/cm² after hot corrosion at 1173k for 100h. The coating exhibits superior hot corrosion resistance to the Y-Co-modified and Co-modified aluminide coatings. The improved hot corrosion resistance of the Y-Ce-Co-modified aluminide coating is mainly attributed to the synergistic effect of Y and Ce.
