主　　题：Lubricant-infused surface Anodic aluminium oxide Deterioration EIS 

摘      要：This study investigated the deterioration of a lubricant-infused anodic aluminium oxide surface in a 1M NaCl solution for~200 *** 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 *** EIS results also revealed that the defects reduced the corrosion resistance of the lubricant-infused surface considerably.
