Pulsed magnetic field treatment was applied to the cemented carbide (WC-12Co) for enhancing its friction-reducing and anti-wear effect under different friction conditions, including dry, distilled water and nano-Fe₃O₄ particles additive friction. The results show that the friction reduction and anti-wear effect could be enhanced with pulsed magnetic field applied. Especially, with nano-Fe₃O₄ magnetofluid lubrication, the wear volume of workpiece is reduced by 26.8% and the average friction coefficient is reduced by 12.4%. The effect of the pulsed magnetic field on tribological properties is closely related to the oxidation and remanence. It can promote oxidation and forms a protective layer on the friction pair. Furthermore, it can make magnetofluid gather and amplify the lubrication.

对硬质合金（WC-12Co）进行脉冲磁场处理，以增强其在不同摩擦条件下的减摩和抗磨效果，包括干燥，蒸馏水和纳米Fe ₃ O ₄颗粒相加摩擦。结果表明，施加脉冲磁场可以增强减摩和抗磨效果。特别是纳米Fe ₃ O ₄磁流体润滑，工件的磨损量减少了26.8％，平均摩擦系数减少了12.4％。脉冲磁场对摩擦学特性的影响与氧化和剩磁密切相关。它可以促进氧化并在摩擦副上形成保护层。此外，它可以使磁流体聚集并增强润滑作用。
