摘　　要：介绍了钢铁材料表面自纳米化的研究现状、纳米晶化机制和表面自身纳米化技术的应用前景,表明表面自身纳米化能显著提高钢铁材料的表面强度,硬度、耐磨和耐疲劳性能,在化学热处理和电化学防护方面也展示了广阔的应用前景。The research state of self-nanocrystallization technology on iron and steel surface, nano-crystallization principle and the application prospect of surface self-nano-crystallization were introduced. The results show that the hardness, strength and wear-resistance of steel after surface self-nano-crystallization technology can be improved. The application prospect of the technology has greatly foreground in chemical heat treatment and electrochemistry protection.
