摘要	The corrosion behavior of Inconel 690 alloys with trace Al and Ti elements was investigated in borosilicate glass at 1150 degrees C. The results showed that the dimensional losses and average corrosion rates were decreased with trace Al addition, which showed excellent glass corrosion resistance, with an annual average corrosion rate below 0.41 mm/a. Differently, the co-addition of Al and Ti increased the dimensional losses and average corrosion rates from 7 days to 21 days, but decreased at 42 days. The trace Al elements lead to the formation of Al2O3 oxides at the grain boundaries, which hinders the diffusion of Cr3+ along the grain boundaries. The slow diffusion of Cr3+ inhibits the growth of the Cr2O3 oxide film and reduces the number of holes in the substrate, leading to excellent glass corrosion resistance. With the co-addition of Al and Ti, the Ti element enhanced the Cr3+ diffusion from inner to outer and the formation of the inner oxide, resulting in the holes and continuous Cr2O3 particles along the grain boundaries. The substrates near the surfaces were peeled along grain boundaries, leading to worse glass corrosion resistance.
