There are a variety of solid particles in the lubricating oil. How to control these particles is one of the key factors to guarantee the normal operation of machinery and equipment. The present project proposal was based on the nano-tribology and research mechanism of solid particles in lubricating oil, through the way of environmental protection and compositing lubricating of solid - liquid. According to the relationship of nano-composite solid lubricant composition, structure, morphology and friction surface and antiwear & friction reduction it was constructed to control the competitive action advantage of nanometer composite particles of solid lubricant on the friction interfaces in the bio-oil. At the same time, it could be realized the synergy lubrication of multi-dimension and multi-form of solid particles and additives in lubricating oil on the friction surfaces. It was discussed the preparation of core-shell structure of nano-molybdenum disulfide with permanent magnetic microspheres to optimize the process conditions and reveal the mechanism of magnetic microspheres active target to interfacial friction. Using the modern surface analysis technology, it was analyzed the friction state and wear mechanism of nano-particles in micro- or nano-scale, and the wear model of solid particles on the interfacial friction. The research results will provide necessary theoretical support and technical guidance for the long-term lubrication theory of high performance green lubricating oils.
