In this work, a suitable cermet compositions based on TiCN-SiC-TiN-Cr₃C₂-Co-B₄C is identified for cutting tool purpose. The cermets were sintered using spark plasma sintering with the addition of different weight percentages of B₄C (5%, 10%, 15%) in TiCN - SiC - TiN - Cr₃C₂ - Co cermets. The cermets were subjected to the annealing process at three different temperatures of 600 °C, 800 °C, and 1000 °C for a constant soaking time of 4 h to study their thermal stability. All the cermets' compositions showed good thermal stability up to 800 °C and 55% TiCN – 15% SiC – 5% TiN – 5% Cr₃C₂–10% Co – 10% B₄C cermets showed better thermal stability up to 1000 °C. There was a change in microstructure and formation of the oxide phases in the cermets during the high temperature (1000 °C) annealing process and overall lead to a decrease in hardness. The sintered cermets were also subjected to sliding wear in the pin on disk apparatus. EN31 steel disk was used as a counter disk. The wear testing was done at different loads (20 N, 25 N, 30 N, 35 N) and at different sliding velocity (0.55 m/s, 1 m/s, 1.5 m/s, 2 m/s) with a constant track distance of 1000 m. Wear rate was at its highest value of 9.74 × 10⁻⁷ mm³/Nm for the cermet 65% TiCN - 15% SiC - 5% TiN - 5% Cr₃C₂₋10% Co and the lowest wear rate noted was 1.18 × 10⁻⁷ mm³/Nm for cermet 55% TiCN - 15% SiC - 5% TiN - 5% Cr₃C₂₋10% Co – 10% B₄C and the B₄C addition has improved the wear resistance of the cermets.

在这项工作中，基于TiCN-SiC-TiN-Cr ₃ C ₂ -Co-B ₄ C的合适金属陶瓷成分被确定用于切削工具。使用火花等离子体烧结法来烧结金属陶瓷，并添加不同重量百分比的TiCN-SiC-TiN-Cr ₃ C ₂ -Co金属陶瓷中的B ₄ C（5％，10％，15％）。金属陶瓷分别在600°C，800°C和1000°C的三种不同温度下进行退火处理，并持续4 h的均热时间，以研究其热稳定性。所有金属陶瓷的成分在高达800°C的温度下均具有良好的热稳定性，并且55％TiCN – 15％SiC – 5％TiN – 5％Cr ₃ C ₂ –10％Co – 10％B ₄金属陶瓷在高达1000°C的温度下表现出更好的热稳定性。在高温（1000°C）退火过程中，金属陶瓷的微观结构和氧化物相形成发生变化，总体上导致硬度降低。烧结的金属陶瓷在磁盘装置的销钉上也受到滑动磨损。EN31钢盘用作计数盘。磨损测试在不同的负载（20 N，25 N，30 N，35 N）和不同的滑动速度（0.55 m / s，1 m / s，1.5 m / s，2 m / s）下进行并保持恒定轨道距离为1000 m。磨损率在其9.74×10最高值^-7 毫米³ / Nm，用于金属陶瓷65％的TiCN - 15％的SiC - 5％的TiN - 5％的Cr ₃ C ^ _{2 -} 10％的Co和最低的磨损率注意到为1.18 ×10^-7 毫米³ / Nm，用于金属陶瓷55％的TiCN - 15％的SiC - 5％的TiN - 5％的Cr ₃ C ^ _{2 -} 10％的Co - 10％B ₄ C和乙₄ Ç此外提高了金属陶瓷的耐磨损性。
