纳米结构材料摩擦学研究进展

Tribological Behaviors of Nanostructued Mateirals

近10年来,由于潜在的工业应用价值,纳米晶体材料的摩擦磨损性能开始引起科研工作者的重视。很多实验结果证明,当晶粒尺寸细化到纳米量级时,材料显示出与其粗晶态不同的摩擦磨损性能。纳米结构材料的摩擦磨损性能受众多因素的影响,包括晶粒尺寸、硬度、塑性、弹性、表面层组织与成分等。

During the past decade, tribological behaviors of nanocrystalline materials have attracted attention from scientists due to their potential industrial application. Many experimental results show that their tribological properties will be different from, and often superior to those of conventional coarse-grained materials, which can be influenced by several factors, including grain size, hardness, plasticity, elasticity, tribo-layer, composition or structure, and so on.
