In this work, an innovative combination of MAO and spraying was employed. A ceramic intermediate layer was first formed on the surface of TC11 alloy via MAO, followed by spraying fluorinated silica nanoparticles (SiO₂ NPs-PFDTES) and epoxy resin to construct a composite coating with high adhesion, achieving excellent corrosion resistance and anti-icing performance. The surface wettability, layered morphology, elemental distribution, self-cleaning ability, corrosion resistance, and anti-icing mechanism were systematically investigated.
