采用电磁复合场辅助激光熔覆技术在纯铁表面制备了Ni 60涂层。通过改变电磁场强度，研究了电磁场对涂层组织的影响，并利用光学显微镜（OM）和X射线衍射仪（XRD）对涂层的组织和相组成进行了分析。结果表明，施加电磁场后，涂层中出现了花状组织和针状组织，涂层顶部和中部的晶粒略有细化。当电磁场参数为1500 A +0.2T时，涂层中花状组织和针状组织的数量最多，涂层中存在大面积的细晶区。此外，电磁复合场还能搅拌熔池，有效降低气孔率。电磁复合场的施加并没有改变涂层的相组成，涂层的相组成仍为γ-Ni、CrB、Cr23 C6和Ni 2B。
In this paper, Ni60 coatings were prepared on pure iron by electromagnetic compound field assisted laser cladding. The effect of the electromagnetic field on the microstructure of the coating was studied by changing the intensity of the electromagnetic field, the microstructure and phase composition of the coating were investigated by optical microscope (OM) and X-ray diffraction (XRD). The results showed that after applying the electromagnetic field, there were the flower-shaped structures and acicular constituents in the coating, and the grains at the top and middle of the coating were refined slightly. The number of flower-shaped structures and acicular constituents was the largest when the parameter of electromagnetic field was 1500A+0.2T, and a large area of fine grained region was found in the coating. In addition, the electromagnetic compound field could stir the molten pool and effectively reduce the porosity. The application of electromagnetic compound field did not change the phase composition of the coating, and the phase compositions of the coatings were still γ-Ni, CrB, Cr23C6 and Ni2B.
