摘　　要：研究了硼对铬系白口铸铁性能的影响规律,并借助扫描电镜、能谱仪、电子探针和X射线衍射仪等手段,分析了性能与组织之间的关系。结果表明:3种不同含铬量的白口铸铁中,硼元素均提高了试样的铸态硬度;含硼的铬系耐磨铸铁的硬度与其相组成和组织形貌密切相关。The effects of boron on the properties of chromium series white cast iron were researched. The relationship between the property and microstructure was investigated by electron microscope, energy disperse spectroscopy ,electron probe micro analysis and X-ray diffractumeter. The results show that boron can improve the hardness of sample, whichever the chromium contents in white cast iron. The hardness of chromium series wear-resistant cast iron containing boron is closely related to those phase constitute and microstructure morphology.
