Graphite powder has the cause of self -lubrication performance analysis

Graphite powder is a wear -resistant material, and its self -lubrication performance is its most important feature. Graphn powder has a good self -lubrication performance due to its special layer -shaped crystal structure. The following are the analysis of the reasons for the self -lubricating property of graphite powder:The carbon atoms in graphite lattles are arranged in hexagonal on different planes. The distance between the carbon atoms in the same plane layer is 1.42 meters, and the distance between the carbon atom of each plane layer is 3.35. They are staggered along the same direction, repeat the position of the first plane in the third plane, the fourth plane repeats the position of the second plane, and so on. In each plane layer, because the carbon atoms are relatively tight, the binding forces between them are relatively large, and the carbon atom between layers and layers is far from each other, which is easy to separate and relatively slide. This is the main reason why gr
