中文摘要:研究了电磁感应熔渗法制备的V8C7增强钢基复合材料的组织和性能,并探讨了复合材料的组织形成机理。结果表明,用电磁感应熔渗法,制备得到了V8C7硬质相,其颗粒细小,尺寸为3~8 μm,且在基体中均匀分布,有利于提高复合材料的组织稳定性。相对于高碳钢标准试样,复合材料的耐磨相性能有了改善。
英文摘要:V8C7/Fe composite were synthesized by electromagnetic induction melting. The microstructure, wear resistance and forming mechanism of the composites was analysed and discussed. The results show that, the hardening phase of V8C7 particles prepared by in-situ reaction distribute along V wires. The V8C7 particles are in small shape and in the size of 3~8 μm, which can raise the microstructure stability of V8C7/Fe composite. The wear resistance of the composite is better than that of the matrix.
