Graphite is hexagonal, frictional coefficient is 0.05 ~ 0.19, in flakey, Stability Analysis of Structures, carbon atom combines securely, be not easy to destroy, layer is more weak with inter-layer bonding force, is easy to slippage by shear action, surface of friction has and well fills and repair, easily forming mulch film in metallic surface, is a kind of good solid lubricant.
Graphene is a kind of novel material of the individual layer sheet structure be made up of carbon atom, by individual layer atomic building, is interconnected to hexagonal gridding between carbon atom, and its proportion in grease is lower.
The structure of molybdenumdisulphide is the same with graphite, is hexagonal, and how carefully no matter grind, have laminate structure definitely, under pressure friction, have very strong avidity to metallic surface, bearing pressure is 3.45 × 10
9pa.The parts of coating molybdenumdisulphide can operate in without oily situation, and under certain temperature and pressure, molybdenumdisulphide and metallic surface occur to react instantaneously, generate the solid film that frictional coefficient is extremely low, prevent metallic surface phase mutual friction sintering.
