| overview | the key to reduce the friction and wear of moving parts under the condition of boundary lubrication is the anti-wear and anti-friction additive in lubricant. good anti-wear and anti-friction agent can effectively reduce its friction and wear. Rare earth materials have received extensive attention due to their special physical and chemical properties, and the study of tribological properties of rare earth compounds has also attracted great interest. At present, the research of rare earth compounds in tribology has penetrated into the fields of wear-resistant metal materials, wear-resistant polymer materials and wear-resistant ceramic materials. However, the research as lubricating additives has just begun at home and abroad, especially the research on oil-soluble organic rare earth antiwear agents, which is the frontier subject of tribology and has broad development prospects in theory and application. At the same time, China is also a big country of rare earths, from the development and utilization of domestic rich rare earths. |
