Abstract:

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.
