【摘要】 为了研究高硼铸钢的耐磨性,借助光学显微镜、X衍射分析仪(XRD)等手段研究了热处理工艺对高硼铸钢耐磨性的影响。实验选用ML-10型销盘磨损试验机,将热处理后的高硼铸钢、高锰钢进行耐磨性对比,研究发现高硼铸钢的耐磨性与高韧性低碳马氏体及高硬度相-硼化物Fe2B密切相关,热处理能显著改善高硼铸钢的强度、硬度。研究结果表明:在冲击磨损条件下高硼钢比高锰钢有较好耐磨性。更多还原

【Abstract】 In order to investigate wear resistant of ligh-boron casting steel,the influence of heat-treatment on wear resistant of high-boron casting steel have been investigated by means of optical microscopy,electron probe micro-analyzer(EPMA) and X-ray diffraction(XRD).Comparing with high manganese steel,high chromium cast iron on ML-10.The results showed that high toughness martensite and high hardness boride were the main contributors to better wear resistance.Furthermore,heat treatment could improve the hardness,strength.After impact abrasion,high-boron steel is more wear resistance than high manganese steel.更多还原
