摘要(Abstract)：

通过滚滑磨损试验机、X射线衍射仪、扫描电镜、微米划痕仪等研究了新开发的重载贝氏体车轮的滚滑磨损性能，并与传统珠光体重载车轮进行对比。结果表明：贝氏体车轮的耐磨性优于珠光体车轮，贝氏体车轮的磨损机制为粘着磨损伴随轻微疲劳磨损，珠光体车轮磨损机制为严重疲劳磨损伴随氧化磨损。磨损后，两种车轮表层组织均发生塑性变形，其组织和强韧性沿表层深度方向呈梯度变化，越靠近表面组织细化越严重，且硬化程度越高。贝氏体车轮具有更高的抗塑性变形和加工硬化能力。珠光体车轮磨损后表层材料位错密度提升了3.89倍，贝氏体车轮则提升了7.27倍。贝氏体车轮中的残留奥氏体通过相变诱导塑性(Transformation Induced Plasticity, TRIP)效应提高车轮硬度的同时减小磨损，有利于提高车轮的耐磨性。
