submicron metal

It is discovered that, under a lower temperature, the metal is lubricated mainly by WS2 adsorption membrane which is formed between metal friction surfaces besides crystal interior layer slipping of WS2 submicron particle in the grease.

发现在较低的温度下，润滑脂中所含的WS2亚微米粒子除了依靠晶体内部层间滑移减少摩擦外，主要依靠在金属摩擦表面形成WS2吸附膜，以起到润滑作用。

The nano-sized PTFE particle generat metal fluoride, forms physical boundary film and repair the injured surface. Submicron-sized PTFE works as rolling element, micron-sized PTFE hinders relative motion of the friction surfaces due to the distortion from pressing.

纳米PTFE微粒通过生成金属氟化物、微粒修复作用和形成物理边界膜，亚微米PTFE通过滚动体作用。微米PTFE在摩擦副间发生变形而阻碍摩擦表面相对运动。
