Özet

The optimum laser parameters required for the inconel 625 alloy surfaces to have the desired properties have been determined. Process parameters were optimized to get maximum heat affected zone depth (HAZ) and width and maximum aspect ratio and minimum defect outside of the spot area independently of each other. Also, the effect rates of the examined process parameters on the treated surface quality were determined separately for each surface feature. As a result of optimization using Taguchi method, the most effective parameters to obtain the desired surface were obtained as gas type with 72.26 % for heat affected zone depth, gas type with 90.46 % for heat affected zone width, gas type with 81.57 % for aspect ratio, pulse energy with 30.99 % for minimum defect outside of the spot area. The best results were obtained on the surfaces obtained as a result of the confirmation experiment with the new parameters obtained with the Taguchi method. Since the results of the confirmation experiments are highly compatible with the results suggested by the Taguchi method, the Taguchi method may be concluded as reliable in the laser ablation of the inconel 625 surface.
