摘　　要：文章综述了无机镧化合物、有机镧化合物、复合镧化合物以及镧化合物与传统添加剂复配的摩擦学性能研究进展,介绍了镧化合物作为极压抗磨剂在摩擦副表面的润滑机理,提出研究开发镧化合物极压抗磨剂需探索绿色合成方法和绿色化合物,兼具高性能、高产率、低成本特性的建议。In this paper,the research progress of tribological properties of inorganic lanthanum compounds,organic lanthanum compounds,complex lanthanum compounds,and compounding of lanthanum compounds with traditional additives is reviewed.The lubrication mechanism of lanthanum compound-based antiwear(AW) and extreme pressure(EP) additives on the surface of friction pairs is introduced.Finally,recommendations for the research and development of lanthanum compound-based EP/AW additives are proposed,that is,to explore green synthesis methods and green compounds with high-performance,high-yield and low-cost properties.
