This research explores laser-induced surface processing to modify surface properties, enhancing the durability and performance of Pulsed Electric Field (PEF) systems. PEF systems use electromagnetic pulses to lyse bacterial cell walls for food pasteurization. However, electrode corrosion and biofouling pose challenges. This study investigates laser-induced oxidation to mitigate metal ion release during PEF operations. The research focuses on three core areas: (1) expanding a thermokinetic model to predict oxide layer composition and color, (2) optimizing laser oxidation to improve corrosion resistance, and (3) integrating the modified surface into a PEF system. A model for Nd:YAG laser oxidation of 316L stainless steel was developed using a factorial Design of Experiments (DoE). X-ray photoelectron spectroscopy (XPS) and optical reflectance spectroscopy determined elemental composition and color variations. Oxide layers exhibited a Cr/Fe ratio from 0.13 to 4.5, with controlled color changes via single-pass laser processing. Further, corrosion resistance was analyzed through laser processing, examining surface chemistry, morphology, and electrochemical properties. Factorial DoE analysis showed lower areal energy samples had superior corrosion resistance and minimal defects, confirmed by cyclic polarization and electrochemical impedance spectroscopy (EIS). Finally, PEF trials integrated DoE, morphological analysis, metal ion release (via ICP-QMS), waveform capture (DAQ system), and impedance spectroscopy. Pulse waveform variations demonstrated a three-fold reduction in metal ion release in laser-treated samples. This study offers key insights into optimizing laser parameters to enhance corrosion resistance and surface chemistry, improving metal performance in PEF systems. These advancements contribute to sustainable food processing by extending PEF system lifespan while maintaining efficiency and product quality.
