摘　　要：介绍了当前世界硬质合金工业的现状及近十五年来的技术进展。估计现在全世界的硬质合金年产量约为 330 0 0t。比十年前增长了约 10 %。如果不考虑前苏联地区 ,世界其余地区的年增长率近十年约为2 4 %。介绍了瑞典山特维克 (Sandvik)公司、美国肯纳金属 (Kennametal)公司、以色列依斯卡 (Iscar)公司及日本硬质合金工业概况。较为详细地介绍了近十五年来粉末原料制取工艺、超细硬质合金、梯度组织硬质合金、表面涂层工艺 (CVD和PVD)、成形工艺及生产过程自动化等六方面工业生产的技术进展。The status quo of the cemented carbide industry in the world and its technical progress in the late fifteen years were presented. It is estimated that the annual production of cemented carbide is about 33000 t worldwide today and increases 10% than ten years ago. The annual growth rate is about 2.4% excluding that of the former Soviet Union. The cemented carbide industry in Sweden, Japan, US and Israel is described. The production technique progress in the late 15 years is presented, including powder production technology, ultrafine cemented carbide, gradient structure cemented carbide, coating technology (CVD and PVD), forming technology and production process automation. WC-6%Co, WC-8%Co and WC-5%β-5%TiN-Co are taken as examples in the research and analysis.
