摘要
采用分子动力学方法对表面涂覆纳米Cu-Zn层铜基复合材料的摩擦磨损性能进行模拟研究,分析了超高载荷前期阶段Cu-Zn层铜基复合材料磨损量的非线性变化原因;同时得出超高载荷后期阶段的磨损量变化,表明无论是前期还是后期阶段,Cu-Zn层铜基复合材料均表现出很好的摩擦稳定性;并通过MD(Molecular dynamic)模拟手段验证了实验分析得到的复合润滑层的存在,为表面涂覆纳米层复合材料的摩擦磨损试验提供了很好的验证与理论指导。
The friction and wear performance of copper-matrix composites with Cu-Zn nanocrystalline surface is research by Molecular Dynamic（MD） simulation. The relationship between the superhigh load and wear mass loss is analyzed; the result is validated that the composite self-lubricating layer have been gotten by friction experiment.
