摘要
石黑晶体中存在着各种类型的缺陷, 在非真空条件下,石墨晶体将自发地吸收和镶嵌各种气体分子和原子,这一现象在其晶体表面尤为突出,特别是能使被吸附物在石墨表面形成一层以化学吸附为主的薄膜,从而大大降低石墨的摩擦系数。
The graphite crystals can spontaneously absorb and imbed different kinds of gas molecules and atoms under non- vacuum conditions owing to the presence of crystal defects in the graphite crystals. The chemically adsorbed molecules or atoms form a thin film on the surface of crystals, which helps reduce the friction factor of graphites to a great extent.
