Durable　superhydrophobic　anti-erosion/anticorrosion　coatings　are　highly　demanded　across　various　applications.　However,　achieving　coatings　with　exceptional　superhydrophobicity,　mechanical　strength,　and　corrosion　resistance　remains　a　grand　challenge.　Herein,　a　robust　microstructure　coating,　inspired　by　the　cylindrical　structures　situated　on　the　surface　of　conch　shell,　for　mitigating　erosion　and　corrosion　damages　in　gas　transportation　pipelines　is　reported.　Specifically,　citric　acid　monohydrate　as　a　pore-forming　agent　is　leveraged　to　create　a　porous　structure　between　layers,　effectively　buffering　the　impact　on　the　surface.　As　a　result,　the　coating　demonstrates　remarkable　wear　resistance　and　water　repellency.　Importantly,　even　after　abrasion　by　sandpaper　and　an　erosion　loop　test,　the　resulting　superhydrophobic　surfaces　retain　the　water　repellency.　The　design　strategy　offers　a　promising　route　to　manufacturing　multifunctional　materials　with　desired　features　and　structural　complexities,　thereby　enabling　effective　self-cleaning　and　antifouling　abilities　in　harsh　operating　environments　for　an　array　of　applications,　including　self-cleaning　windows,　antifouling　coatings　for　medical　devices,　and　anti-erosion/anticorrosion　protection,　among　other　areas.
