摘　　要：用改进的MLD-10型冲击腐蚀磨损试验机,在铁矿石、石英砂和稀硫酸溶液中,对低碳高合金钢、中碳合金钢以及高锰钢进行了冲击腐蚀磨损实验。比较三种钢在不同冲击时间下的失重量和冲击腐蚀磨损表面形貌,结果表明,短时间内,无论哪种介质,低碳高合金钢的冲击腐蚀磨损性能最优越;而在较长时间(8h)内,介质颗粒硬度较小或无颗粒时,低碳高合金钢的耐磨损性能比其余两种钢要优越,但在颗粒硬度较大的介质中,高锰钢表现出较强的耐腐蚀磨损性能。The impact corrosion and abrasion behavior of steels, which are low carbon high alloy, medium alloy steel and high manganese steel, were investigated on a MLD-10 impact-wearing machine in different slurries. The morphology of the worn surface was examined by SEM. The results show that in whatever slurries, the impact corrosion and abrasion behavior of the low carbon high alloy steel is better than other two steels in the slurries with lower hardness impact particle or without impact particle, however, when the hardness of impact particle in the slurry higher, impact corrosion and abrasion behavior of the high manganese steel is better than that of the other steels.
