Abstract Scope |
This study evaluates the role of B4C -modified TiCN- Si3N4- Cr3C2-Co cermet for use in cutting tool applications. Three cermet compositions containing B4C at 5, 10, and 15 wt.% were developed using Vacuum Hot Pressing. Pin-on-disk wear testing was performed on the prepared cermet using EN31 steel as the disc material. The sliding velocities used for the wear testing were 0.31 m/s, 0.94 m/s, and 1.57 m/s, with a constant load of 30N. During wear testing, the cermet composition 60TiCN-15Si3N4-5Cr3C2-5Co-15 B4C (all in wt%) demonstrated the least mass loss. By conducting annealing studies on the prepared cermet at various temperatures, such as 600, 800, and 1000 °C for a constant time with soaking time of 4 hours, the thermal stability of the cermet was evaluated. Up to 800 °C, the prepared cermet exhibited excellent thermal stability. The composition 65TiCN-15Si3N4-5Cr3C2-5Co-10B4C displayed greater thermal stability than the other two cermet compositions. |
