摘要
制备纳米/超细晶WC-Co类硬质合金的两大关键因素是优质纳米/超细晶WC-Co复合粉末的制备和烧结过程中晶粒长大过程的控制。从纳米/超细晶WC-Co复合粉末的制备技术和纳米/超细晶硬质合金的烧结技术两方面,综合评述了近年来国内外的研究进展,并展望了纳米/超细晶硬质合金的发展前景和今后研究开发的重点。
The two key factors for the preparation of nano/ultrafine WC-Co cemented carbides are the preparation of high-quality nano/ultrafine WC-Co composite powders and the control of grain growth during sintering.The research progress at home and abroad in recent years is comprehensively reviewed on nano/ultrafine WC-Co composite powder preparation methods and nano/ultrafine WC-Co cemented carbide sintering technologies.Additionally,the development prospects and the future research focus of nano/ultrafine WC-Co cemented carbides are also discussed.
