摘要：

The hot corrosion process of nickel-base superalloy with different Ti content by coating with salt membrane was studied. The results show that the hot corrosion resistance of the superalloy increases greatly under the experimental condition of 900 degrees C after adding 0.55% Ti. Its hot corrosion resistance becomes better with the increasing of Ti content. Continuous and compact Cr2O3 layer can be formed on the surface of the superalloy by adding titanium. Thickness of Cr2O3 layer increases and Al2O3 layer transfers outward with more Ti, so that the hot corrosion resistance of the alloy increases.
