Cutting tools: finite element modeling of spark plasma sintering to improve their quality

Abstract

This article describes the numerical simulation of the spark plasma sintering (SPS) of the samples of alumina and tungsten carbide powders in the form of square plates with three different radii of curvature at the vertices of 0.8, 1.2 and 1.6 mm. For each of the samples, the temperature distribution of mechanical stresses in the sample and in the mold was obtained. These results can be used to assess the theoretical possibility of sintering inserts by the SPS technology.
