Zusammenfassung:The invention relates to the field of coating preparation, and discloses a preparation method of a corrosion-resistant coating of an electronic component in a marine environment, which comprises the following steps: S1, injecting ions into a mixed layer: preparing a surface binding layer of the component by adopting an ion injection technology, injecting elements including Cu, Ni, Cr and Ag metal elements, a uniform mixed layer with high binding force is formed on the surface of an electronic component through ion implantation of Cu, Ni, Cr and Ag metal elements, and a compact film is formed on a substrate through a high-power pulse magnetron sputtering technology, so that the binding strength and compactness of the coating can be greatly improved; a conductive layer is prepared through high-power magnetic control, and an anti-corrosion layer is deposited through a high-power pulse magnetron sputtering technology, so that the coating prepared through the method is high in binding force and corrosion resistanc
