Abstract: Graphite has been widely utilized in the area of lubrication, but it is prone to oxidation at high temperatures, resulting in lubrication degradation and failure. Therefore, the key to high-temperature lubricating performance improvement is how to enhance the oxidation resistance of the graphite at high temperature. In this work, the raw graphite sheet was treated with the high temperature resistance inorganic phosphate under ball milling assistance, and the treated graphite based lubricant with lubrication function over a wide temperature range was prepared by mixing inorganic phosphate binder and treated graphite fillers. Results by TG, Raman, SEM and CSM tests indicate that, compared with the untreated graphite fillers, the thermal stability and wear life of the treated graphite are significantly increased at high temperatures, the treated graphite composite coatings show excellent thermal stability and lubrication performance under high temperature conditions.
