Laser Cladding Bio-Ceramic Coating Process Parameters Selection Based on Simulation of Temperature Field
Based on the characteristics of laser cladding bio- ceramic coatings, the two- dimensional ribbon heat source is chosen to study and calculate the physical properties of material′s change curves under different temperatures, and the temperature field model is established. The experimental and the simulated results of the prepared coatings are compared in terms of preparation of coatings results in simulative and coating appearance, micro- hardness, bonding strength with substrate and coating phase, which demonstrates the reliability of the model. According to the simulation results, the following conclusion is drawn: both of laser power and scanning speed will affect the depth of molten pool, but the influence of laser power is greater than that of scanning speed. Based on the change trend analysis of simulation, the laser cladding process parameters are P=1700 W, V=165 mm/min. The depth of molten pool under different coating thicknesses and process parameters is simulated and forecasted.
