摘要
用感应加热熔敷方法在Q235钢表面制备了微 纳米碳化钨复合涂层,并分析了涂层的微观结构、显微硬度及耐磨性。结果表明:涂层的组织主要由镍基固溶体和碳化钨颗粒组成。涂层与基体冶金结合;微 纳米碳化钨涂层的耐磨性比微米碳化钨涂层平均提高0.5倍。
Micro-nanostructured WC composite coatings were successfully fabricated by induced heating sintering method on the surface of Q235 steel. The microstructure, micr-hardness and wear resistance of the composite coatings were studied. The results show that the microstructure of induced heating layer is mainly composed of Ni-based solid solutions and WC particles. And there exists excellent metallurgical bonding between coating and substrate. The wear resistance of micro-nanostructured WC composite coatings is increased by 0.5 times on an average as compared with that of micro structured coatings.
