摘　　要：在我国,每年设备、配件的使用磨损、腐蚀及表面失效造成材料损失高达上亿万吨,为了提高耐磨材料的性能,将宏观的摩擦磨损现象与金属组织的微观变化相联系,用动态金属学的观点研究磨损的微观机制,即进行摩擦金属学研究,是揭示金属材料磨损本质的基本途径,有助于耐磨材料和耐磨处理方法的选择和研究开发。基于对高Cr、低Cr和Cr-Mo-Cu耐磨铸铁所进行的摩擦金属学研究,结果表明:利用纳米改性技术可以改善铬系耐磨铸铁的组织结构和性能,尤其是提高铬系耐磨铸铁的耐磨性方面效果明显。该研究为高铬铸铁和Cr-Mo-Cu合金铸铁等材料耐磨性能的提高提供了一条有效途径。Aimed at improving wear-resisting material performance for reducing the an annual loss of millions of tons of materials due to wear, corrosion, and surface failure of industrial equipment and com- ponents, this paper is a dynamic metallurgical study of micro-mechanism of friction and wear by combi- ning the macro phenomena of friction and wear with the micro-structural changes. The tribo-metallurgieal study functions as the basic way to reveal the nature of metal material wear and makes for the selection and development of wear-resistant materials and wear-resistant treatment method. The tribo-metallurgical study of high-Cr, low-Cr and Cr-Mo-Cu cast irons suggests that the use of nano-modification technology provides a significant improvement in the microstructure and properties of chromium cast irons, especially in its wear resistance.
