摘要
采用改进的MLD-10型冲击腐蚀磨损试验机,模拟湿磨工况条件,对新型衬板材质低碳高合金钢和传统材质高锰钢的抗冲击腐蚀磨损特性进行了研究。比较两种材料试样在一定时间内的失重变化情况,表明低碳高合金钢的抗冲击腐蚀磨损性能优于高锰钢。另外分析了冲击腐蚀磨损面形貌、磨面表层及亚表层的状态变化,发现两种材料的冲击腐蚀磨损机制有明显差异,并且都随时间变化而发生转变。
Under wet ball mill conditions, corrosive impact abrasion behavior of a newly developed low carbon high alloy steel liner material were researched with a modified MLD - 10 wear tester, and comparison with the traditional high manganese steel was made. Wear loss of specimens for these two steels during a certain time show that low carbon high alloy steel is much more resistant to corrosive impact abrasion than high manganese steel. Besides, SEM morphology of worn surfaces and metallography of subsurface zones were observed after test, which shows that corrosive impact abrasion mechanisms of these two kinds of steels differ greatly and may both change along time.
