本文研究了相对密度为78%～82%,开孔率大于95%的多孔钨的生产工艺;用扫描电镜观察了钨粉颗粒在工艺过程中的形态、结构变化;根据观测结果对其烧结机理进行了分析。
In this paper, the production process of porous tungsten with a relative density of 78% -82% and an open porosity of more than 95% has been studied. The morphological and structural changes of tungsten powder particles have been observed by scanning electron microscopy. The sintering mechanism Analyzed.
