| Abstract Scope |
The purpose of this work is to investigate the application of laser micro- and nano-machining techniques in the production of modified stainless steel surfaces with regulated wettability and oxide layer composition. We employed a simple one/two-step strategy to build micro, nano, hierarchical patterns, and laser-induced periodic surface structures (LIPPS) on stainless steel. Designs of experiments (Box–Behnken approach), were used to optimise the laser parameters. Developed structures were later characterised for their bio-corrosion properties using electrochemical analysis such as potentio-dynamic polarization, electrical impedance spectroscopy (EIS), and Mott-Schottky (M-S) experiments. X-ray photoelectron spectroscopy (XPS) was used to evaluate the surface composition of the passive layer. Wettability, and surface roughness studies were done to correlate the enhanced anti-bacterial efficacy of laser ablated surfaces. Thus, the higher fidelity approach presented in this work provides a new avenue for the facile design and development of superior surface modification techniques for food storage and bio-applications. |
