The low density graphite gets higher friction coefficient and bulk worn loss than the high density graphite.

低密度石墨的摩擦系数和体积磨损量比高密度石墨材料高。

Another mechanism promoting the formation of the equilibrium phase graphite is surface diffusion which becomes stronger anyway at higher temperatures, especially in areas with high defect density.

促使平衡相石墨形成的另一个机理是表面扩散。不管怎样，此扩散在高温，尤其是在缺陷密度高的区域更明显。
