Characterization of graphite–chromium carbide composites manufactured by spark plasma sintering

Abstract: This manuscript contains an investigation about the influence of the chromium content on the properties of novel graphite–chromium composites obtained by spark plasma sintering (SPS), with great potential application in heat dissipation. Green compacts of 40 mm in diameter were first obtained by uniaxial pressing at 60 MPa, and then the composite was sintered at 1800°C in SPS under vacuum conditions and a pressure of 30 MPa. These sintering conditions involved local liquid phase, which promoted the densificati… Show more

“…The results showed improved elastic modulus, flexural strength, and electrical conductivity in samples containing carbides, Asbury-MoC and Asbury-Cr 3 C 2 . [28][29][30][31] This is related to the fact that the presence of carbides chemically attached to graphite particles can provide bridges in all space directions (x,y,z) [28][29][30][31][32] positively impacting mechanical properties. Moreover, carbides are good electrical conductors, and their dispersion in the compound can increase electron transference, enhancing the electrical conductivity.…”
