主　　题：Pipeline steel Bioinspiration Slippery surface Self-healing 

摘      要：Superhydrophobic surfaces(SHS)and slippery lubricant-infused porous surfaces(SLIPS)attract great attention due to their multiple properties in both industries and our daily ***,we first fabricated the SHS with micro-scale flower-like structures composed of nano-sheets on pipeline steel ***,we obtained the SLIPS by spin-coating lubricant into gaps of micro-scale flower-like structures,with the air still trapped among gaps of *** SLIPS shows excellent liquid repellency as the *** SLIPS also shows stability after the scour of flowing *** results of polarization curves(Tafel)and electrochemical impedance spectroscopies deduced the SLIPS with better and more stable anti-corrosion property than the *** with the SHS,the lack of attachment and CaCO_(3) on the SLIPS indicates that the SLIPS demonstrates better anti-fouling and anti-scaling properties than the ***,the SLIPS shows promising wear resistance under the abrasion simulated by sandpaper compared with the ***,the air trapped among nano-sheets is conducive to the lubricant flowing to the surface quickly,exhibiting spontaneous self-healing in atmosphere,even if part flower-like structures of the SLIPS subject to damage with the lubricant consumed after scratched.
