Abstract

The rise of green manufacturing and the wide use of hard-to-cut materials put forward higher requirements for tool performance. Therefore, it is imperative to develop green and efficient technology to improve tool performance. In this paper, a coupled electromagnetic treatment (CEMT) which can improve the cutting performance of coated cemented carbide inserts is proposed, and the effect of this technology on the static and dynamic performance of coated carbide inserts is studied. The experimental results show that after CEMT, the cutting force of the tool is reduced by 5.7%, and the service life is increased by 40.2%. The bonding strength of the coating increased by 25.9%, the nanohardness increased by 29.6%, the friction coefficient decreased by 25.7%, and the wear rate decreased by 21.3%. Quasi-in situ elemental analysis showed that CEMT increased the width of the coating diffusion zone by 0.2 μm. The main reason for the improvement in tool performance is the higher coating bonding strength and hardness, which is a result of the diffusion of coating elements facilitated by CEMT. The electric field promotes the migration of elements, while the magnetic field increases the chemical potential gradient. CEMT realizes the synergistic effect of electric and magnetic fields, so the strengthening effect is better than a single electric or magnetic treatment. This work provides a clean and efficient method for improving the properties of coated cemented carbide.
