现代烧结技术在制备超细和纳米硬质合金中的应用

Application of modern sintering techniques in fabrication of superfine and nano-sized cemented carbide

介绍了用于制备超细和纳米硬质合金的现代烧结技术,如压力烧结、场辅助烧结、微波烧结、 二阶段烧结等,评价了各种烧结方法,并以实验依据论证了真空烧结等普通烧结工艺在纳米硬质 合金制备中的可行性。

In this paper some modern sintering techniques as well as their properties for nano-grained cemented carbide such as pressure sintering, field assisted sintering, microwave sintering and two-phase sintering were summarized. In addition, more attentions should be paid to the feasibility of conventional sintering such as vacuum sintering in nano-sized cemented carbide technique according to the results of our experiments.
