Paragraph starter

Research by Zhang et al. (2023) demonstrates that optimizing laser cladding parameters, specifically increasing scanning speed, significantly enhances the corrosion resistance of 316L stainless steel coatings. This optimization leads to a refined microstructure with reduced porosity and altered grain morphology, resulting in a substantial improvement in corrosion potential, a decrease in corrosion current density, and a marked increase in pitting potential. This highlights the critical role of precise manufacturing control in achieving desired material performance for demanding applications.
