Abstract：The corrosion behaviors of Inconel 625 alloy in Na2SO4+K2SO4(mol ratio:8∶2) at 750 ℃ for 60 h were tested by X-ray diffraction(XRD), scanning electron microscopy(SEM) and energy disperse spectroscopy(EDS), which provide theoretical basis for related researches In the initial stage of corrosion, the mass of Inconel 625 alloy increased sharply However, after the initial stage, the speed of the corrosion gradually decreased The oxidizing layer of Cr2O3 on the surface of the specimen was incontinuous, allowing the O and S into the matrix and react with the matrix, so there was a significant corrosion in the Inconel 625 alloy at last
