| Abstract: | Distribution regularity of temperature field of laser remelted Ni-coating,oriented by jet electroforming of 45 steel,was studied according to the heat transfer theory and numerical simulation method.Considering the thermophysical parameters,heat convection and phase-change latent heat,computing model of transient temperature field of 3D moving jet electroplated coating laser remelting was build up with Finite Element Method.Laser remelting experiment was carried out with the optimized parameters in the model,and the performance and character of the sample of laser remelted Ni-coating were also studied. |
