The invention discloses a loading method and application of a metal surface corrosion inhibitor. The loading method comprises the following steps of: depositing a layer of inert and porous nano oxide film on a metal matrix; performing saturation adsorption of a corrosion inhibitor through impregnation; and covering a protective layer on the surface. The nano oxide film is prepared by depositing an aqueous solution of precursor such as SiO2, TiO2 or ZrO2 on the metal surface through an electro-deposition method. The corrosion inhibitor adsorbed on the nano oxide film is determined by the type of the metal matrix. The protective layer for covering can be a common organic silane film, an inorganic/organic hybridized silane film or a common organic coating. The loading method for the metal surface corrosion inhibitor is used for protecting metals. A preparation process is simple, and the cost is low. When the matrix is corroded, the nano oxide film can release the corrosion inhibitor to protect the matrix; and compared with a mode that the corrosion inhibitor is directly absorbed on the surface of the metal matrix, the nano oxide layer can load more corrosion inhibitor to better protect the metal matrix.
