The effects of rapid pulse electric current sintering (PECS), Ni as a Co binder substitute, Mo₂C additions and laser surface modification (LSM) on the microstructure, mechanical properties and machining performance during roughing and finishing turning of Ti-6Al-4 V were investigated. Additions of Mo₂C reduced the carbide grain size from 0.65 ± 0.01 μm to 0.5 ± 0.01 μm in liquid phase sintered (LPS) WC-Co/Ni cermets, with the PECS manufactured WC-0.5Cr₃C₂–3.5Mo₂C-10Co (wt%) having the highest hardness. The LSM technique produced a ~2.5 μm self-carbide coating, increasing the surface hardness of all the samples. LSM was done to improve abrasion, attrition and thermal wear resistance. Turning was done at cuttings speeds (v_c) of 45–120 m/min, depths of cut (a_p) of 0.25–2.0 mm and feeds of 0.15–0.2 mm/revolution, under lubricated conditions. The developed inserts were compared to TH10 (an industrial reference), and performance was assessed by cutting forces, tool wear and tool life. The liquid phase sintered WC-0.5Cr₃C₂-10Co (wt%) and WC-0.5Cr₃C₂–3.5Mo₂C-10Co (wt%) inserts had longer tool lives than TH10 during roughing at a cutting speed (v_c) of 45 m/min, depth of cut (a_p) of 2 mm and feed of 0.2 mm/revolution, although TH10 had the best tool life during finishing (v_c = 120 m/min, a_p = 0.25 mm and feed =0.15 mm/revolution). Generally, LSM had a negligible effect on tool life, WC-Ni based inserts had the shortest tool lives and LPS inserts performed better than PECS inserts.

快速脉冲电流烧结（PECS），Ni作为Co粘结剂的替代品，Mo ₂ C的添加和激光表面改性（LSM）对Ti-6Al-4粗加工和精加工过程中的组织，力学性能和加工性能的影响V被调查。在由PECS生产的WC-0.5Cr ₃ C ₂ –3.5Mo _2的液相烧结（LPS）WC-Co / Ni金属陶瓷中，Mo ₂ C的添加将碳化物晶粒尺寸从0.65±0.01μm减小到0.5±0.01μm。具有最高硬度的C-10Co（wt％）。LSM技术产生了约2.5μm的自硬涂层，从而提高了所有样品的表面硬度。进行LSM是为了改善耐磨性，耐磨性和耐热磨损性。在润滑条件下，车削的切削速度（v _c）为45-120 m / min，切削深度（a _p）为0.25-2.0 mm，进给量为0.15-0.2 mm /转。将开发的刀片与TH10（工业参考）进行比较，并通过切削力，刀具磨损和刀具寿命评估其性能。液相烧结WC-0.5Cr ₃ C ₂ -10Co（wt％）和WC-0.5Cr ₃ C ₂ –3.5Mo ₂C-10Co（wt％）刀片在以45 m / min的切削速度（v _c），2 mm的切削深度（a _p）和每转0.2 mm的进给量进行粗加工时，具有比TH10更长的刀具寿命。在精加工期间具有最佳的刀具寿命（v _c  = 120 m / min，_p  = 0.25 mm，进给量= 0.15 mm /转）。通常，LSM对刀具寿命的影响可忽略不计，基于WC-Ni的刀片的刀具寿命最短，而LPS刀片的性能优于PECS刀片。
