4种成分车轮钢与U71Mn钢轨钢间的磨损行为
Wear Behavior between Wheel Steels with Four Chemical Composition and U71Mn Rail Steel
摘 要
在轮轨磨损试验机上研究了热轧U71Mn钢轨钢和4种成分车轮钢间的摩擦磨损行为，分析了车轮钢化学成分、硬度对磨损行为及磨损机制的影响。结果表明：随着碳元素含量的提高，车轮钢显微组织中先共析铁素体含量显著减少，珠光体晶粒尺寸增大，珠光体中的渗碳体片层变厚，车轮钢的硬度也逐渐增大；随着车轮钢硬度的增大，车轮钢磨损量减少，其主要磨损机制由磨粒磨损和浅层剥层磨损向深层剥层磨损转变，钢轨钢磨损量增加，其主要磨损机制为浅层剥层磨损。

Abstract
The friction and wear behavior between the wheel steels with four chemical composition and hot-rolled U71Mn rail steel was studied using a wheel/rail wear tester, and the effects of wheel steel composition and hardness on the wear behavior and wear mechanism were analyzed. The results show that with the increase of carbon content, the proeutectoid ferrite content reduced obviously, the pearlitic grain size increased, and the thickness of cementite lamella also increased in the microstructure of the wheel steel, resulting in the increase of wheel steel hardness. With the increase of wheel steel hardness, the wear loss of the wheel steel decreased and the main wear mechanism changed from abrasive wear and shallow delamination wear into deep delamination wear, while the wear loss of the rail steel increased and the main wear mechanism was shallow delamination wear.
