Researchers from the R&D Center of Lubricating and Protecting Materials at the Lanzhou Institute of Chemical Physics (LICP) of the Chinese Academy of Sciences (CAS) have fabricated a bonded graphite solid film lubricant with excellent high temperature lubricating and anti-wear properties. They have received a Chinese invention patent for the preparation technique on March 7.

The lubricant consists of polyamidoimide, graphite, molybdenum disulfide, rare earth fluoride, metal oxide, and mixed organic solvent.

With its excellent high temperature lubricating and anti-wear properties, the lubricant can work at 250℃ for a long time. Moreover, the lubricant has abrasion resistance, thereby playing roles in protecting surface to reduce abrasion and friction coefficient, and prolonging service life of parts.

The lubricant can be used to prepare coatings with excellent high temperature lubricating and anti-wear properties. And these properties make it possible for the coatings to work under medium-high temperature lubricating environment. In this way, the coating can be used in rotors and endplates of air-conditioner compressors of which the running conditions involves high temperature, high load, high speed, special medium, etc, thereby improving the early running of rotors and endplates of air-conditioner compressors, reducing the damage to them and prolonging their service life.
