摘要
叙述了矿用硬质合金的应用领域和近年来的生产状况,介绍国内硬质合金的生产工艺,指出硬质合金应以超粗晶、梯度结构和双粘结相结构为主攻方向,工艺技术更需创新提高。
the paper describes the areas of application and production of cemented carbides for mine and presents the manufacturing processes of cemented carbides in China. Extra-coarse grain, gradient structure, and twin-binder phase shall be set as the main developmental directions for the cemented carbides and innovation and improvement are needed in the process and technology.
