摘　　要：钼及钼合金的高温氧化问题限制了其应用。MoSi2因其优异的高温抗氧化性能被认为是最适合工程应用的高温涂层材料。本文介绍了MoSi2的物理性能、抗氧化机理及其作为涂层材料的制备工艺,综述了国内外钼及钼合金表面MoSi2的单一及复合抗氧化涂层的研究进展,并对其未来发展方向进行了展望。The poor high temperature oxidation resistance of molybdenum and its alloys limits their applications. MoSi2 is considered to be the most suitable high - temperature coating material because of its excellent high temper- ature oxidation resistance. Physical properties, mechanism of oxidation resistance and coating preparation technolo- gies of MoSi2 are summaried. The research progress on the Mosi2 oxidation resistance coating of molybdenum and its alloys is reviewed, including MoSi2 sole coating and MoSi2 composite coatings. The research trend of MoSi2 coating in the future is forecasted.
