| 摘 要： | 以片层状NbSe2为原料, 通过粉末冶金复压复烧的方法制备出不同质量分数的NbSe2/Cu复合材料。对复合材料的显微结构、物理性能及摩擦磨损性能进行了研究。结果表明, NbSe2的加入可显著提高材料的摩擦学性能。这是由于复合材料在摩擦热和变形挤压的共同作用下, 基体中NbSe2被逐渐挤出, 形成了NbSe2的固体润滑膜。NbSe2表面镀Cu可提高NbSe2与Cu基体的界面结合强度, 所形成的固体自润滑膜不易脱落且更加完整, 从而使复合材料具有更优异的物理性能和摩擦学性能。

| Abstract: | Different mass fractions of NbSe2/Cu composite were made from NbSe2 sheets by repressing and resintering process of powder metallurgy. Physical and tribological property and microstructure of NbSe2/Cu composites were investigated. The results show that the friction coefficient and wear rate are greatly reduced by the addition of the NbSe2 sheets. This is due to the enrichment of NbSe2 in the surface of the composite and the forming of a solid lubricating film by the combined effect of frictional heat and extrusion. When the NbSe2 sheets are coated with copper, the interfacial combination between NbSe2 and Cu-matrix is improved and thus the composite will have better physical and tribological property. |
