Abstract

Spark Plasma Sintering (SPS) is an advanced consolidation technique that efficiently densifies powders using pulsed DC current and pressure at lower temperatures and shorter durations than conventional methods. It promotes diffusion, minimizes grain growth, and preserves microstructures, making it suitable for ceramics, metals, and composites. SPS has been successfully applied to high-entropy alloys, novel ceramic composites, nanocrystalline titanium, porous metallic scaffolds, silicon germanium alloys, and aluminum-matrix composites, leading to improved mechanical, electrochemical, and thermoelectric properties. Understanding plasma effects and optimizing SPS parameters are key to achieving desired material characteristics.
