摘　　要：LaF3纳米材料作为一种新型的润滑油添加剂显示出了优异的摩擦学性能。文章综述了近年来LaF3纳米材料的制备方法、表面改性技术以及润滑作用机制和应用进展,指出LaF3纳米材料在润滑中所面临主要问题是它的分散性和稳定性问题。展望了LaF3纳米材料作为润滑添加剂的发展趋势。随着现代工业的快速发展,LaF3纳米颗粒作为极压抗磨剂是未来的发展方向,在摩擦学领域中它的摩擦学性能和润滑机理必将受到人们更为广泛的关注。LaF3 nanomaterials have shown excellent tribological properties as a kind of new additive in lubricating oil and grease. The preparation method, surface- modification technology, lubricating mechanism and application development of LaF3 nanomaterials are summarized in this paper, it is pointed out that the key problems of LaF3 nanoparticles in lubricant are the dispersity and stability. The future development of LaF3 nanomaterials as lubricating oil additive is presented as well. With the accelerative development of modern industry nowadays, LaF3 nanomaterials will be a young conception in the field of tribology. And the tribological properties and lubricating mechanism will be gotten more and more attention.
