Abstract
We have systematically investigated the process parameters of laser cladding CPM 10V on AISI 1045 steel substrates. Based on experimental results, we have made reasonable approximations and assumptions, developed a simple but realistic process model, relating the maximum clad thickness and various process parameters, for on-line production. The predicted results of this model are in good agreement with the experimental results. A 2.5 kW continuous-wave: CO 2 laser, a coaxial powder feeding system, and a CAD/CAM system were used for laser cladding experiments. The microstructure of cladding layer, interface and heat-affected zone are characterized by using optical microscopy. Microhardness measurements of laser cladding samples under different treatment conditions are also carried out.
