采用空气等离子喷涂技术（APS）在钼基体上制备了mosi2氧化防护涂层。研究并测定了涂层的显微组织、相组成、孔隙率、显微硬度和结合强度。研究了涂层在高温下的氧化行为。结果表明：涂层主要由mosi2和Mo5Si3组成，表面形貌表现为平整的片层特征，表面粗糙度不够平整的凸起，有一定数量的球形颗粒、微裂纹和气孔；结果表明：随着功率的增大或氩气流量的减小，涂层的显微硬度和结合强度增大，孔隙率减小；随着孔隙率的降低，涂层的显微硬度也随之提高。涂层的结合强度随喷涂距离的增加而增加。在1200°C时，mosi2mo衬底具有良好的抗氧化性能。
MoSi2oxidation protective coatings on molybdenum substrate were prepared by air plasma spraying technique (APS). Microstructure, phase composition, porosity, microhardness and bonding strength of the coatings were investigated and determined. Oxidation behavior of the coating at high temperature was also examined. Results show that composition of the coatings is constituted with MoSi2and Mo5Si3, the surface morphology is described as flattened lamellar features, insufficiently flattened protuberance with some degree of surface roughness, a certain quantity of spherical particles, microcracks and pores. Testing results reveal that microhardness and bonding strength of the coatings increase, and porosity decreases with increasing power or decreasing Ar gas flow rate. Moreover, with decreasing the porosity, the microhardness of the coatings increases. The bonding strength of the coatings also increases with increasing spray distance. The MoSi2coated Mo substrate exhibited a good oxidation resistance at 1200 °C.
