Abstract：
Ferrous alloys, particularly steels, form a specialized class of metallic materials extensively employed in industrial sectors to combat deterioration and failures caused by wear. Despite their commendable mechanical properties, steels are not immune to wear-induced degradation. In this context, surface nanocrystallization (SNC) technologies have carved a distinct niche for themselves by enabling the nanostructuring of the surface layer (with grain sizes < 100 nm). This process enhances overall mechanical properties to a level desirable for wear resistance while preserving the chemical composition. Existing literature has consistently highlighted the efficacy of various SNC methods in improving the wear resistance of ferrous alloys, positioning SNC as a promising tool to extend materials\' service life in practical applications. This review provides a comprehensive examination of the SNC techniques employed in surface treatment of ferrous alloys and their impact on wear behavior. We delved into the underlying mechanisms governing wear in SNC-treated Fe-based alloys and concluded with a discussion on current challenges and future perspectives in this evolving field.
摘要：
铁合金,特别是钢，形成一类专门的金属材料，广泛应用于工业部门，以对抗磨损引起的劣化和故障。尽管它们的机械性能值得称赞，钢不能幸免于磨损引起的降解。在这种情况下，表面纳米化（SNC）技术通过实现表面层的纳米结构（晶粒尺寸<100nm），为自己雕刻了一个独特的利基。该方法将整体机械性能提高到耐磨性所需的水平,同时保持化学组成。现有文献一直强调各种SNC方法在提高铁合金的耐磨性方面的功效，将SNC定位为在实际应用中延长材料使用寿命的有前途的工具。这篇综述全面研究了用于铁合金表面处理的SNC技术及其对磨损行为的影响。我们深入研究了控制SNC处理的铁基合金磨损的基本机制，并在这个不断发展的领域中讨论了当前的挑战和未来的前景。
