摘要
材料的磨损起源于表面,金属材料的摩擦磨损性能与表面结构密切相关。利用表面纳米化(Surface nanocrystallization)技术可以在金属材料的表面制备出一定厚度的纳米结构表层,从而大大提高金属的耐磨性。结合国内外学者的研究报道,综述了表面纳米化在金属耐磨性方面的影响,讨论了表面纳米化方法与机理以及表面纳米化影响耐磨性的因素,简述了应用表面纳米化技术改善各种金属材料耐磨性的研究和实用成果,最后进行了总结和展望。
Wearing stems from surface of material, the friction and wear properties of metallic materials are closely related to their surface structure. Nanostructured layer with a certain thickness can be produced by means of surface nanocrystallization technology on surface of metallic materials to enhance their wear resistance distinctly. With the research work of scholars, an overview of the influence of surface nanocrystallization on wear resistance of metallic materials is given. The methods, principle and factors influencing wear property of surface nanocrystallization are dis- cussed, the research achievements and applying results are illustrated, and the summary and prospect are presented at last.
