摘要：

The corrosion behavior of Inconel 625 alloy have been investigated in molten (Li, K)(2)CO3 and (Li, K)(2)CO3 + Y2O3 at 650 degrees C by SEM and XRD. Results show that the corrosion rate of Inconel 625 alloy in molten (Li, K)(2)CO3 is faster than that in the (Li, K)(2)CO3 + Y2O3 at 650 degrees C. The excellent corrosion resistance of the Inconel 625 alloy in (Li, K)(2)CO3 + Y2O3 at 650 degrees C is related to the formation of a protective oxide film of NiCr2O4, Y2O3, NiO and Cr2O3.
