Keywords

metal matrix composites, high voltage electric discharge, spark plasma sintering, copper, titanium, titanium carbide, hardness

Abstract

Metal–matrix composites based on copper with Ti–TiC fillers synthesized by high-voltage electric discharge were produced by spark plasma sintering. The effect of filler content (2–10 wt.%) on structure, hardness, and electrical resistivity was studied. Increased Ti–TiC content improved hardness from 43 to 68 HRB, with resistivity rising from 0.184 to 0.300 Ω·mm²/m.
