摘要
综述了目前国内外梯度硬质合金涂层基体的发展现状及其制备方法 ,对梯度硬质合金涂层基体的烧结过程热力学、梯度硬质合金涂层基体制备过程中重要的工艺参数以及梯度形成机理进行了详细讨论。
The development and fabrication methods of gradient cemented carbides and several crucial problems which are encountered during the sintering of the gradient cemented carbides and cermets in China and other countries were summarized in this paper. The thermodynamics, preparation processing parameters and the formation mechanism of the gradient structure of the cemented carbides were also discussed in detail. Finally, some aspects in the investigation and production of the gradient cemented carbides and cermets which deserve special attention were pointed out. Ti-W-C-N is taken for example in the research and analysis.
