| 英文摘要 | In this present, the oxidation behaviors of TiAlNb intermetallics with and without sputtering NiCrAlY and TiAlCr coatings and enamel coating at 800 degrees C and 900 degrees C respectively were studied. The results indicate that TiAlNb bare alloy has the ability to resist oxidation at 800 degrees C and 900 degrees C by forming the adhesive layered oxide scale of Nb-doped TiO2 and Al2O3. And the three coatings could protect TiAlNb intermetallics from oxidation at the two temperatures. However, heavy interdiffusion occurr at the interfaces of coatings/TiAlNb after oxidation. A continuous protective Al2O3 scale formed at part of interface of NiCrAlY/TiAlNb to hinder the interdiffusion and the inward-diffusion of oxygen. A protective Al2O3 scale could form on TiAlCr coating during oxidation at elevate temperature. However, the interdiffusion of Nb and Cr at the interface might be detrimental to the long-term oxidation resistance and mechanical performance of the substrate. Enamel coating could provide protection to TiAlNb alloy due to its good thermal chemistry stability and matched thermal expansion coefficient with the substrate. But reaction layer occurred at the interface of enamel/TiAlNb would weaken the adhesive ability of coatings to the substrate. |
