Abstract

Abstract

The oxidation behavior and oxidation kinetics of FGH95 P/M alloy at different temperatures were investigated by TGA method, X-ray diffraction, SEM, and EDS analysis. The results showed that FGH95 alloy had good antioxidation characteristics in the temperature range of 800-1 000℃, and its oxidation kinetic curve obeyed a parabolic rule. When the temperature increased up to 1 100℃, the antioxidation property of FGH95 alloy decreased and its oxidation kinetic curve exhibited two parabolic segments. XRD, SEM, and EDS analysis indicated that the oxidant layer was mainly composed of Cr₂O₃ and TiO₂, and little amount of NiCr₂O₄ was formed at 1100℃.
