钢结硬质合金是以难熔金属碳化物(TIC或WC)作硬质相,以钢为粘结剂,用粉末冶金工艺制取的一种新型工具材料。其结构特点是细小的主要起耐磨作用的金属碳化物硬质颗粒弥散分布在具有一定强度和硬度的起支撑作用的钢基体上。此类合金综合了硬质合金和钢的优点,而弥补了它们的不足。主要用于制造各种工、模具和耐磨零件,能获得良好的技术经济效果。 钢 Steel bonded carbide is refractory metal carbide (TIC or WC) for the hard phase, steel as a binder, powder metallurgy process using a new tool material. Its structure is characterized by small, hard-wearing metal carbide hard particles dispersedly distributed on a supporting steel substrate having a certain strength and hardness. Such alloys combine the advantages of cemented carbide and steel to make up for their deficiencies. Mainly used in the manufacture of various workers, molds and wear parts, access to good technical and economic results. steel
