摘要

This study investigated the deterioration of a lubricant-infused anodic aluminium oxide surface in a 1 M NaGl 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.
