Spray-on fabrication of superhydrophobic (SH) coatings using nanoparticles (NPs) has broad applications, but their mechanical durability often falls short of practical requirements. In this work, we demonstrate that mixing NPs with well-dispersed SiC whiskers (SiCw) can significantly improve the SH stability and mechanical durability of sprayed coatings, even under complex and harsh impact/abrasion conditions (such as sandblasting), which is attributed to the formation of a fully connected, avian nest-like, self-similar SiCw framework via the random packing of whiskers during coating drying. The resulting coating exhibits exceptional abrasion resistance, enduring 1,000 dry and 900 wet cycles in Taber abrasion tests (CS-17 wheels), and shows negligible degradation after impact testing at 3.12 × 10
