    Abstract:

    In order to study the effect of steady magnetic field on Fe element distribution in laser cladding Inconel 718 coatings. A three-phase mixed solidification model based on volume average method was established. The steady magnetic field was coupled into the laser cladding process to simulate the preparation of Inconel 718 coatings on 316L stainless steel. The 2D transient model, combined with heat and mass transfer, fluid flow and Induced Lorentz force, was used to simulate the distribution of element in the laser cladding coatings and compared with the experimental results. The results show that the Fe element content in the cladding layer is uniform when no magnetic field is applied; However, the Fe element content in the cladding layer is uneven when the steady magnetic field is applied, the Fe element content in the top of the cladding layer is lower than that in the bottom of the cladding layer. The simulation results are in good agreement with the experimental results, which proves the reliability of the calculation model. It also shows that the steady magnetic field can inhibit the flow of the molten pool, affect the heat and mass transfer of the moving molten pool, and ultimately change the element distribution in the laser cladding coating.
