英文摘要Fe-basedamorphous coatings are ideal materials for surface protectiondue to their outstanding mechanical properties and corrosion resistance.However, coating defects are inevitably formed during the preparationof coatings by thermal spray technology, which seriously affects thecorrosion performance. Inspired by bionics, conceiving superhydrophobicsurfaces with liquid barrier properties has become a new idea forthe corrosion protection of metal surfaces. In this work, based onsurface hydroxylation, we designed a superhydrophobic Fe-based amorphouscoating with corrosion resistance by chemical etching combined witha thermally driven preparation strategy. The obtained superhydrophobiccoatings exhibit liquid repellency (contact angle >150 & DEG;) andexcellent corrosion resistance (corrosion current density and passivecurrent density reduced by 3 orders of magnitude). The results revealedthat the superhydrophobic behavior stems from the construction ofhydroxyl-induced surface micro-/nanomultilevel aggregates (clusterstructures). The hydrophobic agent layer deposited on the surfaceof cluster aggregates and the nanoparticle elements that constitutethe clusters dominate the corrosion resistance of the coating. Thiswork provides an effective guide to the design of high-corrosion-resistantFe-based amorphous alloy coatings and promotes their engineering applications.
