摘　　要：浸锑石墨材料作为高温耐磨密封材料特别适合发电厂中速磨煤机的动密封。对国内外2种浸锑石墨材料的组织结构、机械性能和摩擦磨损性能进行了对比分析,结果表明国内浸锑石墨材料达到国外同类产品的先进水平,可以代替进口件用于中速磨煤机,同时提出了浸锑石墨材料的研究方向。The graphite /antimony composites are excellent wear resistance seal materials at high temperature and suitable for dynamic sealing in medium speed coal mills of power plants. Some aspects are analyzed, including the microstructure, mechanical properties and friction - wear behavior between the home - made specimen and the German specimen. The results indicate that the properties of the home - made product have reached the advanced level of the foreign product. The home - made product can be used in medium speed coal mills replacing the foreign product.
