Abstract:

This study investigated the deterioration of a lubricant-infused anodic aluminium oxide surface in a 1?M NaCl solution for 200 days. Direct observation by cryo-SEM and quantitative analyses by UV spectroscopy and EIS revealed that the long-term deterioration of the lubricant-infused surface was divided into two stages: the surface-adhered lubricant layer gradually dissolved at a constant rate until the substrate was exposed; afterwards the lubricant infused in the nanochannels began to diffuse and was depleted after 200 days. The EIS results also revealed that the defects reduced the corrosion resistance of the lubricant-infused surface considerably.
