中文摘要:
      利用脉冲电磁耦合处理设备对WC-8Co硬质合金进行强化处理。通过测试WC-8Co力学及摩擦性能,再利用采集到车削试验中的切削力、温度及后刀面磨损量信号对干车削Ti6Al4V的切削行为进行了分析。最后采用SEM和EDS对WC-8Co硬质合金进行观测与分析得出脉冲电磁耦合处理前后WC-8Co硬质合金干车削Ti6Al4V切削机理。结果表明:脉冲电磁耦合处理能提升刀具耐用度,降低切削温度及刀具后刀面氧化磨损。
Study on Cutting Mechanism of WC-8Co Cemented Carbide for Dry Turning of Ti6Al4V Before and After Pulsed Electromagnetic Coupling Processing
英文关键词:Pulsed electromagnetic coupling  WC-8Co carbide  Ti6Al4V  Cutting mechanism
英文摘要:
      Pulsed electromagnetic coupling treatment equipment was used to strengthen WC-8Co cemented carbide. The mechanical and frictional properties of WC-8Co were studied, and the strengthening mechanism was revealed by analyzing the cutting performance. The cutting behavior of Ti6Al4V in dry turning was analyzed by collecting the cutting force, temperature, and wear signals of the flank surface on the tool in the turning test. Finally, scanning electron microscopy(SEM)and energy-dispersive X-ray spectroscopy(EDS)were used to observe and analyze the WC-8Co cemented carbide. The aim was to obtain the cutting mechanism of WC-8Co cemented carbide for dry turning of Ti6Al4V before and after pulsed electromagnetic coupling processing. The results show that pulsed electromagnetic coupling processing can improve the durability of tools while reducing the temperature of the cutting and the oxidation wear of the flank surface of the tools.
