摘　　要：利用改造的冲击腐蚀磨损机,测试了不同冲击功下含稀土量为0.08%的改性高锰钢的冲击腐蚀磨损性能。结果表明,在模拟实际工况条件下,当冲击功为1.2 J时,改性高锰钢的冲击腐蚀磨损机理为微观犁皱和二次显微切削,腐蚀作用不明显。当冲击功为2.0 J时,改性高锰钢的冲击腐蚀磨损机理为挤出棱加工硬化造成的材料剥落。在低冲击功下,改性高锰钢具有优异的耐冲击腐蚀磨损性能,是一种优良的冶金矿山用湿式球磨机衬板用钢。The property of impact-corrosion and abrasion of modified high manganese steel containing 0.08%RE was tested in different impact power by reconstructive impact-corrosion resistance machine.The results show that,under the simulated working condition of metallurgical industry,when impact power is 1.2 J,the impact-corrosion and abrasion mechanism of the steel is micro-plough and second micro-cutting,and there is no erosion abrasion.When impact power is 2.0 J,the impact-corrosion and abrasion mechanism of the steel is characterized by spalling of extruded hardened edge.The modified high manganese steel has a good property of impact-corrosion resistance in the low impact power.It is a kind of good skateboard steel for wet-grinding machine in the circumstance of metallurgy and mine.
