An electromagnetic coupling treatment for improving the cutting performance of cemented carbide-coated tools

To improve the cutting performance and prolong service life of a carbide-coated tool in process ductile iron machining, an electromagnetic coupling treatment (EMCT) was carried out. The experiments show that force temperature are reduced after EMCT, roughness machined surface is reduced. It found EMCT with optimal parameters dislocation density, microscopic strain, microhardness bonding strength alumina coating increase by 109.2%, 28.2%, 28.3% 26.6%, respectively. Using actual machining differential housing to verify life, it single can 18.4 more workpieces or other words, increased 44%. promote element diffusion, optimize properties have great potential extension.
