通过场激活加压燃烧合成技术,采用不同钨碳摩尔比例的反应体系,来致密化碳化钨材料。研究了温度、反应物组成对产物组成、密度和显微硬度的影响,结果表明,最终产物的相对密度在81.1％和84.2％之间,样品在9.8N作用下的维氏硬度在731和498kg·mm-2之间。
Activation by pressure field combustion synthesis technology, the use of different tungsten and carbon molar ratio of the reaction system to densification of tungsten carbide material. The effects of temperature and reactant composition on the composition, density and microhardness of the product were investigated. The results showed that the relative density of the final product was between 81.1% and 84.2%. The Vickers hardness of the sample under the action of 9.8 N was between 731 and 498 kg · Mm-2 between.
