Abstract

The effect of low-frequency pulsed magnetic treatment on micro-hardness of W9Mo3Cr4V(W9) high speed steel (HSS) has been investigated. A low-frequency pulsed magnetic treatment system was designed and applied to treat the tool material. Experiments were conducted at different magnetic field intensities and pulse frequencies. Experimental results show that the low-frequency pulsed magnetic treatment can effectively increase the micro-hardness of W9 HSS in a proper treatment parameters. The micro-hardness change rate first increase and then stabilize as the magnetic field intensity increases. Pulse frequency has little effect on the treatment effect.
