Technology of self-repairing and reinforcement of metal worn surface

Abstract

Researches on self-repairing material (serpentine phyllosilicate) of our team in the past few years, such as ultrafining treatment, surface modification, self-repairing mechanism, the effect of rare metal on the self-repairing performance of serpentine, were introduced summarily. The phyllosilicate of serpentine shows excellent tribological and self-repairing performance for metal worn surface as additive in lubricant.
