Spark Plasma Sintering of CoCrNi–TiC Cermet

Key Points

This research aims to explore the mechanical enhancements of CoCrNi–TiC cermet synthesized via spark plasma sintering.
Cermet synthesized using spark plasma sintering techniques.
Mechanical properties evaluated, including Vickers hardness and fracture toughness.
Achieved Vickers hardness of 16,320 MPa, significantly higher than CoCrNi's 2025–2332 MPa.
Fracture toughness ranged between 8.12 and 10.60 MPa m1/2, indicating good material resilience.

Abstract

CoCrNi–TiC cermet was synthesized by spark plasma sintering, resulting in the formation of secondary chromium-rich (CoCrNi)3C2 phase during consolidation. The cermet was found to exhibit a markedly enhancement in mechanical properties, achieving a Vickers hardness of 16 320 MPa compared to 2025–2332 MPa for CoCrNi, while preserving a fracture toughness of 8.12–10.60 MPa m1/2. This strengthening effect is directly attributed to the reinforcing role of TiC grains within the composite structure.
