| 英文摘要 | Two kinds of Cr2AlC coatings with different microstructures were prepared by direct crystallization during oxidation at 1000 degrees C and conventional crystallization at 700 degrees C for 1 h for amorphous Cr-Al-C coatings prepared by magnetron sputtering, respectively. The effect of microstructure on the oxidation behavior of the coatings at 1000 degrees C was investigated. The grain boundary density and dislocation density of the Cr2AlC coatings crystallized directly during oxidation were much higher, which provided much more sites for heterogeneous nucleation of alpha-Al2O3 and fast diffusion paths for Al. Therefore, the coating formed complete pure alpha-Al2O3 scales earlier with better antioxidant properties. More importantly, the present work demonstrates feasibility and advantages of directly applying amorphous Cr-Al-C coatings at high temperatures without additional crystallization treatments, which simplifies preparation process of Cr2AlC coatings, facilitates their industrial applications, and provides a new method for rapid preparation of MAX-phase coatings. |
