[0002] Lubricating powder can be used in places where lubricating grease cannot be used, in harsh environments and in situations where maintenance is not required, due to its excellent friction performance, high load-bearing capacity and wear resistance, good wide temperature characteristics and timeliness. Lubricating powder can be applied to the surface of the object to be lubricated to form a lubricating film on its surface to alleviate the friction between the contact surfaces.
