The Fe106+5%Ni/WC composite coatings are prepared on the 304 stainless steel surfaces by the rotating magnetic field assisted laser deposition technique, and the changes of their macro-morphologies, microstructures, microhardness, and friction and wear properties under different magnetic field rotating speeds are investigated. The results show that, the rotating magnetic field has a small effect on the surface roughness of the deposition layer when the magnetic field strength is 70 mT and the magnetic field rotating speed is 100-400 r·min -1. With the further increase of the magnetic field rotating speed, the surface roughness of the deposition layer gradually decreases, the melt width increases, and the wetting angle gradually decreases, which indicates the surface quality is obviously improved. In addition, the microhardness of the deposition layer gradually increases with the increase of the magnetic field rotating speed. When the magnetic field rotational speed is 600 r·min -1, the average hardness microhardness of the deposition layer reaches 825 HV, which is about 1.178 times that of the magnetic field free deposition layer. Simultaneously, the wear quality of the deposition layer gradually decreases, and the minimum average weight loss is only 2.2 mg, which is 1.33 times higher than that of the magnetic field free deposition layer.
