AB  - Lubricant (or oil)-impregnated porous surface has been considered as a promising 
      surface treatment to realize multifunctionality. In this study, silicone oil was 
      impregnated into a hard porous oxide layer created by the plasma electrolytic 
      oxidation (PEO) of aluminum (Al) alloys. The monolayer of polydimethylsiloxane 
      (PDMS) from silicone oil is formed on a porous oxide layer; thus, a 
      water-repellent slippery oil-impregnated surface is realized on Al alloy, showing 
      a low contact angle hysteresis of less than 5 degrees . This water repellency 
      significantly enhanced the corrosion resistance by more than four orders of 
      magnitude compared to that of the PEO-treated Al alloy without silicone oil 
      impregnation. The silicone oil within the porous oxide layer also provides a 
      lubricating effect to improve wear resistance by reducing friction coefficients 
      from ~0.6 to ~0.1. In addition, because the PDMS monolayer can be restored by 
      frictional heat, the water-repellent surface is tolerant to physical damage to 
      the oxide surface. Hence, the results of this fundamental study provide a new 
      approach for the post-treatment of PEO for Al alloys.
