Field Activated Combustion Synthesis of Tungsten Carbide (Ⅱ) --Field-activated Pressure-assisted Combustion Synthesis

Abstract

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
