Antifouling plated part as well as preparation method and application thereof

The invention relates to the technical field of antifouling and waterproof materials, in particular to an antifouling plated part and a preparation method and application thereof, and aims to solve the problems that a hydrophobic film layer is insufficient in stability, poor in reliability, not resistant to scraping, easy to damage when being scratched by external force and the like in the prior art. The antifouling plating piece comprises a to-be-plated piece substrate; the metal bottoming layer is arranged on the surface of the to-be-plated piece substrate; the transition layer is arranged on the surface, deviating from the to-be-plated piece substrate, of the metal base layer; the hydrophobic layer is arranged on the surface, deviating from the metal bottoming layer, of the transition layer; wherein the transition layer and the hydrophobic layer are made of inorganic materials, the transition layer and the hydrophobic layer both contain silicon elements, and the surface, away from the transition layer, of
