中文摘要：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。
英文摘要：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.
