Optimization of the Spark Plasma Sintering Process for High-Volume Fraction Tungsten Carbide/Al 2025 Composites

Abstract

With an orthogonal experimental design, Spark plasma sintering method was used to create tungsten carbide with Al 2025 composites. Pressure, temperature, and hold time all had an influence on the mechanical characteristics of the composites. Pressure had the greatest effect on density and bending strength, followed by temperature and holding duration. After five minutes of sintering at 556°C under 40 MPa, a 50% tungsten carbide/Al 2025 composite material was produced, resulting in a density of 997.7 percent and a spectacular bending strength of 766.65 MPa. This study revealed the ability of high-volume fraction mixes to support huge loads.
