The Progress of Research on Boric Compounds as Extreme-pressure Antiwear and Friction-reducing Lubricant Additive

The preparation, properties and current research of boron-type compounds as lubricant additive were reviewed. Their tribological properties, antiwear and friction-reducing performance and tribochemical mechanism were introduced such as the permeation of boron into surface layer of friction pair,the catalysis of rare earth elements for boron permeating and synergy between additives. To improve the anti-hydrolytic ability of boron-type compounds,the methods that the surface of borate particles is modified and the nitrogen atom is intrduced into the molecule of boracic compounds were put forward. The multi-functional boric lubricant additives with sulphur, chlorine, phosphorus or nitrogen atom were mentioned besides the boronized amine salt of thiophosphate, and the environmental effects of boric lubricant additives were pointed out.
