研究了石墨含量对Ｃｕ基滑板烧结膨胀的影响与作用机理，石墨的体积百分数依次为０、７．１％、１２％、１３．５％、１６．６％，其对应的体膨胀率依次为－６．４％、４．６％、１６％、２１％、３２％。膨胀机制是石墨阻碍金属颗粒形成烧结颈，使烧结初期因释放应变能和排放成型剂而引起的膨胀得以保留。烧结膨胀率与石墨含量近似于线性关系 The effect of graphite content on the sintering expansion of Cu-based slide was studied. The volume percent of graphite was 0, 7.1%, 12%, 13.5% and 16.6%, respectively. The corresponding volume expansion rate was -6.4%, 4.6%, 16%, 21%, 32%. Expansion mechanism is graphite hindered the formation of metal particles sintered neck, so that the initial sintering due to the release of strain energy and release of forming agents caused by the expansion of retained. Sintering expansion rate and graphite content is approximately linear
