纳米硬质合金的研究进展

Development in Research on Nano-cemented Carbide

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。

Abstract:

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.
