摘要: 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。

Abstract: The field-activated pressure-assisted combustion synthesis (FAPACS) process was utilized to produce and densify tungsten carbides material from tungsten and carbon powders with different mole ratios. The effects of the temperature, the reactants composition on the products composition, density and microhardness were investigated. The relative densities of end-products are from 81.1% to 84.2%. Vickers microhardness measurements (at 1kg force) on the dense samples gave values from 731kg·mm-2 to 498kg·mm-2.

Key words: combustion synthesis, tungsten carbide, field activation
