纳米WC-Co硬质合金研究现状

Study the current situation in nanostructure WC-Co cemented carbide

综述纳米硬质合金的研究开发概况及应用。重点介绍纳米WC和WC-Co粉体的制备方法和烧结工艺,指出要成功地制备纳米硬质合金,关键在于抑制烧结过程中WC晶粒的长大。简要介绍纳米硬质合金的应用前景。

Summed up the research and development overview and application of the nanostrueture cemented carbide synthetically. Have done the introduction to the preparation method and craft of fritting especially of nanostructure WC and WC-Co powder. To point out, it is prepare to succeed in to want nanostructure cemented carbide, key lie in it is frit course WC crystalline grain grow up to suppress; and has introduced the application prospect of the nanostructure cemented carbide.
