应用逾渗理论和O lympus光学显微镜对石墨基体和浸锑石墨试件进行了显微组织结构的金相分析,结果表明:形成石墨基体孔隙逾渗结构、优化石墨浸锑二次逾渗制备工艺是提高浸锑石墨密封材料的高温摩擦磨损性能的2个重要环节。
The percolation theory and O lympus optical microscopy were used to analyze the microstructure of the graphite matrix and the antimony-impregnated graphite sample. The results show that the porous percolation structure of graphite matrix and the percolation process of graphite impregnated antimony Is to improve the antimony graphite sealing material of high temperature friction and wear properties of the two important links.
