| 中文摘要 | Nb-doped Zr(2)[Al(Si)](4)C(5) solid solutions were prepared by in situ hot pressing method and their high-temperature oxidation behavior at 1000 degrees-1300 degrees C were investigated. The oxidation resistance of [Zr(0.9)(Nb(0.1))](2)[Al(Si)](4)C(5) solid solutions is improved remarkably compared with Zr(2)[Al(Si)](4)C(5) without dopant. The improved oxidation resistance is due to the formation of a more protective oxide scale consisting of (Zr,Nb)O(2), Nb(2)Zr(6)O(17), Al(2)O(3), and mullite, in which (Zr,Nb)O(2) solid solution is more effective than ZrO(2) in depressing the inward diffusion of oxygen. In addition, the decrease of cracks in the oxide scale above 1100 degrees C in Nb-doped sample is also beneficial to the improved oxidation resistance. |
