Abstract

In the present study, pulsed laser ablation in liquid (PLAL) treatment has been optimised for ASTM 304/2B stainless steel using Taguchi method. PLAL experimental trials were carried out using fiber laser source by varying laser parameters include overlap rate, scanning speed, laser irradiation power and the number of laser pulses. The optimum laser parameters have been derived by considering the response which is corrosion potential of metal targets. Analysis of Variance (ANOVA) and signal to noise ratio are used to analyse the effect of different laser parameters on the responses. The laser irradiation power is the most dominant factors affecting the corrosion resistance of stainless steel in neutral solution; the overlap rate is the most significant impact corrosion resistance of metal in acidic solution. The responses of the optimized laser parameters obtained implementing the Taguchi method has been verified experimentally and hence supporting the accuracy of optimization of laser parameters under the given set of experimental conditions.
