Abstract

In this study, investigations were conducted to evaluate a new type of rapid treatment designed to alter the microstructures of cemented carbides for improved milling and mechanical performances. The effects of a treatment that combined a pulsed magnetic field and a pulsed current (MCT) on the milling performance, mechanical properties, and conductivity of the cemented carbides (WC-6Co) were studied. The results show that the wear loss of the cemented carbides decreases by nearly 35 pct and the milling force decreases significantly after MCT. The hardness and transverse rupture strength are enhanced by approximately 2 and 12 pct, respectively. The conductivity of the electromagnetically treated sample exhibits a decrease of 5 pct. Microstructural analysis reveals that the electromagnetic treatment tends to increase the dislocation density within the cemented carbides, which strengthens the material and decreases the conductivity.
