| Abstract | The oxidation behavior of a cast polycrystalline Co-base superalloy was studied at temperatures from 900 to 1050 degrees C and analyzed by thermogravimetric analysis (TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate that a cast Co-base superalloy follows the subparabolic oxidation kinetics at 900 and 1000 degrees C, which are controlled by the growth of the inner Cr-rich layer, and that after oxidation at 1050 degrees C for 200 h, it almost exhibits the linear oxidation kinetics possible due to the volatility of Cr-rich oxide. A mixed scale forms on the alloy after prolonged oxidation. The oxide scale formed at 900 and 1000 degrees C is composed of an outer layer of spinel and an inner continuous Cr-rich layer and at 1050 degrees C is composed of a very discontinuous Cr-rich layer. |
