摘要：

研究了电弧增材制造耐磨钢的组织结构、力学性能和摩擦学性能。结果表明：电弧增材制造耐磨钢试样的外观形貌质量良好，未发现气孔、裂纹等缺陷，试样内部为良好的冶金结合，金相组织主要为马氏体；透射电镜结果显示，电弧增材制造耐磨钢试样的晶体结构为马氏体，试样中存在碳化物、夹杂物和位错；试样截面在纵向和横向显微硬度分布有较大波动，其截面纵向和横向的平均显微硬度分别为601和597 HV0.5；试样的室温屈服强度为1112 MPa，抗拉强度为1259 MPa，室温下试样夏比冲击值的均值为4.2 J；电弧增材制造耐磨钢试样在载荷为5～25 N的摩擦磨损测试条件下的磨损率约为10-6～10-5 mm3·(N·m)-1 量级，摩擦因数为0.24～0.69，具有较好的耐磨性能。

Microstructure, mechanical properties and tribological properties of wear resistant steel prepared by wire+arc additive manufacturing (WAAM) were studied. The results show that the appearance of the wear resistant steel sample prepared by WAAM is of good quality,and no defects such as pores and cracks are found. The inside of sample is a good metallurgical bond, and the metallographic structure is mainly martensite. TEM results show that its crystal structure is martensite, and there are carbides, inclusions and dislocations in the sample. The cross-sectional microhardness distributions of the sample in the longitudinal and transverse directions have large fluctuations, and the average microhardness values of the cross-section in the longitudinal and transverse directions are 601 and 597 HV0.5 respectively. The tensile yield strength of the sample at room temperature is 1112 MPa, and the tensile strength is 1259 MPa, and the average Charpy impact value is 4.2 J at room temperature. The wear rate of the wear resistant steel sample prepared by WAAM is about 10-6-10-5 mm3·(N·m)-1 magnitude in the condition of 5-25 N friction and wear test, and the friction coefficient is 0.24-0.69, which has excellent wear resistance properties.
