摘　　要：在短切莫来石纤维隔热瓦表面采用浆料喷涂法制备了短切莫来石纤维增韧Mo Si_2-Si C-B_2O_3-SiO_2/Mo Si_2-Si C-B_2O_3-SiO_2-SiB_6梯度涂层,并利用XRD、XPS、SEM和EDS对涂层的组成、结构及形貌进行了分析,探讨了涂层的形成机理。分析表明涂层主要由MoSi_2、硼硅玻璃及少量的Mo_(4.8)Si_3C_(0.6)组成。涂层表面及截面的SEM照片表明涂层表层致密,靠近基体部分疏松多孔,部分涂层深入多孔的基体,提高了涂层与基体的结合力。A chopped mullite fiber reinforced MoSi2-SiC-B2O3·SiO2/MoSi2-Si C-B2O3·SiO2-SiB6 multi-component coating was prepared on the surface of.mullite insulation tile by the slurry method. The composition, microstructure and formation mechanism of the multi- component coating were studied by using XRD, XPS, SEM and EDS analysis. The results show that the main phases in the coating are MoSi2, borosilicate glass and Mo（4.8）Si3C（0.6）. The coating shows a dense structure in the surface and a porous structure close to the matrix. Such a microstructure is expected to be of benefit to the improvement of the adhesion strength between the coating and the matrix.
