摘　　要：在耐磨铸钢中添加了0.3wt%纳米铜,通过超声振动辅助搅拌实现了耐磨铸钢的纳米改性,并进行了显微组织观察以及拉伸、冲击和磨损试验。结果表明,在耐磨铸钢中添加0.3wt%纳米铜可显著提高拉伸性能、冲击性能和耐磨损性能。0.3wt% nanometer copper was added in the wear-resisting cast steel. The modified nanometer wear resistant cast steel was realized by ultrasonic vibration assisted mixing. And the microstructure observation and the tests of the tensile, impact and wear properties were carried out. The results show that adding 0.3 wt% of nanometer copper in the wear resistant cast steel can significantly improve tensile properties, impact properties and wear resistance properties.
