Progress in Application Nanoparticles in Lubricating Materials

A review was given on the progress in application of nanoparticles in lubricating materials. Thus the methods to prepare lubricative nanoparticles were introduced. The action mechanisms of the nanoparticles were discussed with respect to transfer film formation, ball bearing-like function, and surface optimization function. The application of the lubricative nanoparticles in lubricating materials was high-lighted. It was pointed out that many kinds of inorganic lubrica-tive nanoparticles could be used as antiwear and friction - reducing additives to improve the tribological behavior of lubricating oils and polymer - matrix composites. At the same time, some lubrica-tive nanoparticles could be used as fillers in non-polymer-matrix composite coatings and endow the coatings with the ability to well adapt to varied environmental conditions, which would make it feasible for the filled composite coatings to find promising application in engineering.
