摘要
利用改造的MLD-10型冲击腐蚀磨损试验机，研究了三种湿式磨机衬板钢的冲击腐蚀磨损行为。研究结果表明：在冲击功为1．7J的模拟工况条件下，低碳高合金钢的耐冲击腐蚀磨损性能要优于高锰钢和以锰代镍低碳高合金钢。从磨损失效机理来看，短时间内，高锰钢的冲击腐蚀磨损机理以显微切削为主，低碳高合金钢的冲击腐蚀磨损机理为浅层剥落。以锰代镍低碳高合金钢的冲击腐蚀磨损机理为多次塑性变形机制。长时间后，高锰钢的冲击腐蚀磨损机理为块状剥落，低碳高合金钢的冲击腐蚀磨损机理为累积变形疲劳剥落，以锰代镍低碳高合金钢的冲击腐蚀磨损机理为疲劳腐蚀剥落。
The behavior of impact corrosion and abrasion of the liner in wet-grinding machine were discussed by means of a modified MLD-10 tester. The results show that, when impact energy is 1.7J, the corrosion rate and the wear loss of the low carbon high alloy steel is better than that of the high manganese steel and that of the low carbon high alloy steel substituting Ni with Mn .Considering the mechanism of wear deterioration, the impact corrosion and abrasion mechanism of high manganese steel is mainly micro-cutting, the low carbon high alloy steel is shallow spalling ,the low carbon high alloy steel substituting Ni with Mn is plastic deformation time aftcr time within shorter time. After longer time,that of the high manganese steel is massive spalling, the low carbon high alloy steel is fatigue spalling resulting from accumulating deformation ,the low carbon high alloy steel substituting Ni with Mn is fatigue-corrosion spalling.
