摘要
概述了纳米硬质合金的研究进展,重点对纳米WC和WC-Co粉体的制备方法、烧结工艺和性能进行了介绍。指出要成功制备纳米硬质合金,关键在于控制烧结过程中WC晶粒的长大,探索新的快速烧结方法。
Much research worldwide is concentrated on nano-cemented carbide due to its excellent properties and promising market prospect. This paper reviewes some developments in nano-cemented carbide. New fast sintering techniques should be employed because the key to obtaining nano-cemented carbide is to control the WC grain growth during sintering.
