采用放电等离子烧结法制备了TiCN基金属陶瓷刀具。研究了各组分对复合材料力学性能和切削性能的影响。结果表明，添加SiCw和La 2 O3可提高TiCN基金属陶瓷的致密度、强度和硬度。与TiCN-5Co金属陶瓷相比，TiCN-5Co-1 SiCw和TiCN-5Co-1 SiCw-1 La 2 O3具有较好的力学性能。切削试验表明，与TiCN-5Co-1 SiCw-1 La 2 O3刀具相比，TiCN-5Co-1 SiCw-1 La 2 O3刀具的切削力显著降低，耐磨性显著提高。
TiCN-based cermet cutting tools were fabricated by spark plasma sintering. The effect of each component on mechanical properties and cutting performance was studied. The results show that the density, strength, and hardness of TiCN-based cermets can be improved by adding SiCw and La2O3. Compare to TiCN-5Co cermets, TiCN-5Co-1SiCw and TiCN-5Co-1SiCw-1La2O3 obtained good mechanical properties. Cutting experiments showed that the cutting force on a TiCN-5Co-1SiCw-1La2O3 tool was significantly reduced compared to that on a TiCN-5Co-1SiCw tool; meanwhile, the wear resistance of TiCN-5Co-1SiCw-1La2O3 was enhanced to a significant extent.
