【摘要】 采用原位合成的方法制备了(Ti,V)C颗粒增强钢铁基复合材料,用XRD,SEM和电子探针研究了该复合材料的物相结构和显微组织,并用MM200型磨损试验机研究了该复合材料的耐磨性能。结果表明:原位合成的(Ti,V)C增强相颗粒细小,尺寸为1~2μm,呈球状,在-αFe基体中均匀分布。在重载干摩擦磨损条件下,该复合材料显示了良好的耐磨性能。更多还原

【Abstract】 The(Ti,V)C particles reinforced iron-based composite was produced in-situ. The microstructure and wear-resistance of the Fe-(Ti,V)C composite were studied by SEM,electron probe and XRD.The results show that spherical(Ti,V)C particles exhibit finer size and homogeneous distribution in the matrix,and under condition of dry sliding with heavy loads,Fe-(Ti,V)C composite shows great wear-resistance.更多还原
