Friction is inevitable physical phenomenon in machinery equipment operation process, not only results in the consumption and meeting of energy
Because prolonged friction produces abrasion and then causes equipment component to be damaged.Parts can reduce equipment under state of wear
The breakdown of work efficiency, reliability and stability, even equipment.According to statistics, due to caused by fretting wear machinery set
Ratio shared by the failure of standby parts is very big, and causes substantial amounts of energy expenditure and loss.Lubricant grease is current society
Maximum, the widest in area lubricant of meeting lubricating area consumption, but grease lubrication there is also the defect of oneself.In some special feelings
Condition such as boundary friction, under the conditions of mixed film friction, it may appear that the directly contact between metal and metal is so as to producing dry friction.Unlubricated friction
Wiping is the friction phenomenon that people most want to avoid.Therefore, under some special lubrication operating modes, the application of solid lubricant coating can be obtained
Obtain the favor of people.
From the eighties in last century, China's researcher has carried out selfreparing skill between associated metal/metallic rubbing pairs
The research of art, and main research application direction is lubricant grease.The relevant selfreparing component of many document patent reports exists
Application and its lubrication mechanism in oils and fatss（Wang Yong etc., metal additive of self-rehabilitation anti-friction Wear vesistance Review Study, manufacturing technology
