摘要
针对矿冶工程用耐磨材料的特点 ,用电冶熔铸工艺研制了新型的碳化钨钢结硬质合金。该工艺可用废弃的粉冶钢结硬质合金做原料 ,低成本生产大体积工件。用扫描电镜、金相观察和X射线衍射等分析方法 ,对加入 40 %WC的试验材料显微组织结构进行了研究 。
In accordance with the characteristics of wear resisting materials in use for mining and metallurgical engineering, a new type of steel-bonded tu ngsten carbide is developed by means of electroslag melting and casting. This ne w techonolog can produce low-cost large volume workpieces using waste steel- bonded carbides of powder metallurgy as raw material. Through optical microscopi c, scanning electron microscopic and X-ray diffraction analyses of microstructu re of the test material alloying 40% wc, it is shown that annealing and forging can improve the alloy's structure.
