Abstract:

The corrosion behavior of Inconel 625 alloy haved been investigated in molten (Li,K)2CO3 and (Li,K)2CO3 Y2O3 at 650℃ by using SEM and XRD.It was shown that the corrosion rate of Inconel 625 alloy in molten (Li,K)2CO3 is faster than that of Inconel 625 alloy in the (Li,K)2CO3 Y2O3 at 650℃.The excellent corrosion resistance of the Inconel 625 alloy in (Li,K)2CO3 Y2O3 at 650℃ was related to the formation of a protective oxide film with NiCr2O4、Y2O3、NiO、Cr2O3.
