Obtaining bulk copper-based composite materials with improved physical and mechanical properties often requires pretreatmentof the initial raw materials. Especially it concerns metal matrix composites (MMC) containing copper as a matrixand silicon carbide as a reinforcing component. However, the final properties of Cu/SiC MMC depend on successful solvingthe problem of silicon solubility in liquid-phase copper during the sintering process. In this work, we demonstrate thepossibility of high-energy treatment of copper and silicon carbide by the plasma dynamic method to obtain a pre-activatedcharge for further sintering. Analytical studies by X-ray diffractomtery (XRD), scanning electron microscopy (SEM), andtransmission electron microscopy (TEM) methods testify to the possibility of obtaining highly dispersed composite Cu/SiCmaterials of different phase and grain size composition depending on the synthesis conditions. The application of polymodalCu/SiC powders pre-activated by the plasma dynamic method as a charge is established to ensure producing bulk samplesby the spark plasma sintering (SPS) method and allow increasing the relative density by ~ 5%–10% and the hardness of thefinal products by more than 30% compared with pure copper samples produced by the same method.
