Abstract

AbstractCarbon steel is widely used, but it is prone to corrosion, which can lead to safety accidents. In this study, a novel Ni‐SiC coating was synthesized on the surface of carbon steel using a one‐step electrodeposition method, and the influence of electrodeposition parameters on the wettability of the coating was investigated. This coating possesses abundant micro‐nanostructures on its surface, which, after being placed in a vacuum drying environment for 2 weeks, endows it with superhydrophobic characteristics. Due to its superhydrophobic properties and the rich micro‐nanostructures, the corrosion current density of this coating is 1/18.95 that of bare steel. After immersion in a corrosive medium for some time, the polarization resistance value of the coated sample was observed to be 13.05 times greater than that of bare steel, demonstrating its remarkable ability to enhance the corrosion resistance of the surface. The results of this study can provide a reference for the anticorrosion work on carbon steel.
