The Evolution of Element Distribution During Laser Cladding Under Static Magnetic Field

The convective transport of heat and mass can be modified under an external magnetic field during the laser cladding process. The cladding of Inconel 718 powder on a 316L substrate under a static magnetic field was numerically studied. The results show that a static magnetic field has little effect on the characteristics of the temperature field, while an uneven distribution of iron concentration was obtained due to the induced Lorentz force inhibiting melt flow.
