Abstract: Fe313 alloy coating was prepared on the surface of 45 steel by using external magnetic field assisted plasma cladding technology. OM(optical microscope), SEM(scanning electron microscope), EDS(energy disperse spectroscopy) and XRD(X-ray powder diffractometer) were used to analyze the microstructure and phase composition of the coating. The microhardness of the coating was tested using a Vickers hardness tester, and the abrasion performance of the coating was studied by friction and wear experiments. The results show: After applying a magnetic field, under the action of electromagnetic stirring, the coarse columnar crystals in the coating are transformed into fine equiaxed crystals, and the grain refining effect is obvious. The coating presents a hypoeutectic structure, including a primary supersaturated (Fe, Cr) solid solution phase and an inter-dendrites eutectic carbide phase (M7C3 type carbide). The external magnetic field makes the eutectic carbide more finely and uniformly distributed on the coating. The microhardness and abrasion resistance of the coatings prepared after the application of a magnetic field were significantly better than those of the coatings prepared without a magnetic field. At a load of 50 N, the wear mechanism of the coating made by the applied magnetic field current of 0 A and 5 A is adhesive wear, and the wear mechanism of the coating made by the applied current of 7 A and 9 A is mixed wear mechanism of abrasive grain wear and slight adhesive wear. When the load is 100 N and 150 N, the adhesive wear of the coating made by the applied magnetic field current of 0 A and 5 A is intensified, and the wear mechanism of the coating made by the applied current of 7 A and 9 A changes from the mixed wear mechanism to the adhesive wear mechanism.
