| 英文摘要 | Cr2AlC coating has potential applications as high temperature protective coating. However, inevitable inter-diffusion at coating/substrate interface promotes Al depletion and deteriorates its oxidation resistance. In the present work, the oxidation behavior of a triple-layered Cr2AlC coating, with (Cr,Al)(2)O-3 inner layer, amorphous intermediate layer and crystalline Cr2AlC outer layer, was investigated at 900 and 1000 degrees C in air. The effect of the (Cr,Al)(2)O(3 )inner layer as diffusion barrier was evaluated during the oxidation process. It is showed that the triple-layered Cr2AlC coating could effectively improve the oxidation resistance of the M38G alloy substrate, due to the Cr2AlC outer layer. The (Cr,Al)(2)O-3 inner layer could prohibit internal nitridation and retard interdiffusion at the coating/substrate interface, improving oxidation resistance of the triple-layered Cr2AlC coating. Furthermore, cracking of the triple-layered Cr2AlC coating was found after oxidation at 900 and 1000 degrees C, due to the thermal stress and internal stress introduced by intermediate amorphous layer crystallization during oxidation. |
