Abstract

In this work we present fabrication of slippery liquid infused porous surface (SLIPS) for anodized stainless steel AISI 316L. First, a porous sponge-like oxide layer was grown that subsequently was functionalized with perfluorinated molecules and finally infused with fluorinated Krytox oil. Morphology, composition analysis and wettability (also after corrosion testing) were characterized. Furthermore, corrosion behavior was studied with potentiodynamic polarization curves in 0.1 M H2SO4 and 0.1 M NaCl electrolytes. Our results demonstrate that the SLIPS coating protects the underlying material from corrosion, and the self-healing properties of the oil layer allow to recover localized damage during corrosion experiments.
