摘要	The hot corrosion behaviors of Co-Al-W superalloys with Re additions were investigated at 900 degrees C. The results showed that the addition of Re improved the hot corrosion resistance significantly. The alloys developed multi -layer oxidation and corrosion products, which located from surface to substrate were: the CoO and Co3O4 layer, the CoWO4 and CoAl2O4 layer, the Al2O3 layer, and the Co3W layer. The addition of Re promotes the formation of the alpha-Al2O3 scale, which is stable and dense. The thickness the alpha-Al2O3 scale in 1Re alloy is 1.9 mu m, which is much thicker than that of the base alloy. The well-developed alpha-Al2O3 scale leads to the improvements in hot corrosion resistance.
