| 摘 要： | 用改进的MLD-10型冲击腐蚀磨损试验机, 在模拟工况条件下, 对不同碳含量的新型衬板用低碳高合金钢冲击腐蚀磨损行为进行了比较; 通过XRD及冲击腐蚀磨损形貌分析, 对其组织和冲击腐蚀磨损机制进行了探讨。结果表明: 碳含量为0.21%的低碳高合金钢具有最佳的抗冲击腐蚀磨损性能, 其冲击腐蚀磨损机制在短时间内为多次塑性变形和显微切削, 长时间后变成疲劳剥层为主, 兼有多次塑性变形、显微切削。 |

| Abstract: | Researches were made on the impact wear properties of low carbon high steels with different carbon contents on simulated conditions by using a modified MLD - 10 impact wear tester. Besides, the microstructure and impact wear mechanism were discussed through X -ray diffraction and SEM morphological analysis on the worn.surfaces. The results showed that the low carbon high alloy steel with 0. 21% C had the best impact wear resistance. The impact wear mechanism is multiple plastic deformation and mild cutting in short time, but mainly fatigue flake - off together with multiple plastic deformation and mild cutting after a long time. |
| Keywords: | impact wear low carbon high alloy steel liner wear mechanism |
