•Y–Ce–Co-modified aluminide coating was prepared by pack cementation method.•The obtained coating exhibits good hot corrosion resistance.•Improved corrosion resistance is attributed to the synergistic effect of Y and Ce.
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 0.32 mg/cm2 after hot corrosion at 1173 k for 100 h. 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.
