Abstract:Magnetic field was introduced in laser melting deposition to reduce the pores in workpieces. Finite 3-D model of the coil-deposition layer-substrate was established. Simulation results show that the electromagnetic force in deposition layer mainly concentrates in the projection area of the coil. Axial electromagnetic force shows repulsion in one cycle. The experimental results indicate that the magnetic field is beneficial for grain refinement, microhardness increasement and decline of quantities and average sizes of pores. © 2018, Editorial Department of Transactions of NUAA.
