Abstract The wear performance and corresponding wear mechanism of a high strength low alloy (HSLA) steel containing Mn, Cr, Ni and Mo are reported here. The wear performance of this newly developed steel is compared with that of a commercially available wear resistant steel (Hardox 400) in dry sliding condition. The tests are run in an ambient environment at various normal loads ranging from 50 to 85 N with a sliding velocity of 0.5 m/s. It is found that the wear rate of the HSLA steel is one-third of that of Hardox 400. The analysis of the worn surface indicates that ploughing, micro-cutting, and oxidative wear are the main wear mechanisms. Phase transition is observed across the worn surface of Hardox 400. The work hardening as well as improved yield strength of the HSLA steel lead to the superior wear performance.

400Hv级马氏体钢力学性能及滑动磨损行为研究

摘要 本文报道了一种含Mn、Cr、Ni 和Mo 的高强度低合金(HSLA) 钢的磨损性能和相应的磨损机制。将这种新开发的钢的磨损性能与市售耐磨钢 (Hardox 400) 在干滑动条件下的磨损性能进行比较。测试在周围环境中以 50 到 85 N 的各种正常载荷和 0.5 m/s 的滑动速度运行。发现HSLA钢的磨损率是Hardox 400的三分之一。对磨损表面的分析表明，耕作、微切削和氧化磨损是主要的磨损机制。在 Hardox 400 的磨损表面上观察到相变。 HSLA 钢的加工硬化以及提高的屈服强度导致了卓越的磨损性能。
