| 摘 要： | 在JD-1型轮轨摩擦模拟试验机上，在赫兹接触条件下，对4种不同含碳量车轮轮箍钢的剥离和磨损性能进行了试验研究．结果表明：磨损量随含碳量的增加而减小；含碳量越高，剥离程度越严重，剥离块越大；降低含碳量，可减轻剥离的发生，但同时会增加车轮的磨损量．

| Abstract: | Spalling and wear behaviors of four kinds of wheel steels with different carbon concentrations were investigated on JD-1 wheel-rail simulating test machine under Hertzian contact condition. The results show that, with an increase in carbon concentration, the wear volume of wheel decreases; but the degree of spalling increases with larger fragments; and decreasing carbon concentration alleviate spalling, but increases wear volume of the specimens. |
