Researches on the Temperature Field during the Process of Reparation by Laser Cladding through Simulation and Experiments

During the laser cladding process, temperature field is an issue worth thorough research. An optimized temperature field can not only ensure the high metallurgical bonding strength between the cladding layer and the substrate, but also can produce relatively mild thermal deformation for the parts to be repaired. This work theoretically analyzes the temperature field during the cladding process and validate the analysis through the microstructure of the cladding layer.
