摘要
通过对在线热处理U20MnH钢轨进行磨损试验研究,并结合显微镜和扫描电镜观测到的试样磨损表面和剖面的形貌特征,分析了不同载荷条件下钢轨的磨损行为特征和变化规律.结果表明:分别在 1 200 N、1 500 N、1 800N载荷的条件下,在线热处理U20MnH钢轨磨损量随载荷的增大而显著减小.
Abstract
The characteristics and change rules of wear behavior for rail with different load conditions are analyzed through experimental study on wear of on line heat treated U20MnH rail combining with the morphology features of wear sur-face and profile for samples observed by microscope and scanning electron microscope.The results showed that the wear loss of on line heat treated U20MnH rail was significantly reduced with increase of load under load conditions of 1 200 N,1 500 N and 1 800 N respectively.
