A method for preparing a bactericidal film having a titanium carbonitride carrier layer on metal comprising preprocessing, polishing, plating a bactericidal film carrier layer and a bactericidal film. The surface of the polished metal is smooth. During the plating process, as silver ions do not react with carbon and nitrogen, through changing the number of carbon and nitrogen atoms, various desired colors of the bactericidal film may be achieved. Subsequently, a nano silver sputtering target is initiated, which enables silver ions with bactericidal effect to be uniformly distributed in the titanium carbonitride film layer, thus forming a colored bactericidal film with bactericidal effect. The workpiece is hung on the hanging rack during the plating process, which allows the rotation and revolution of the workpiece to be simultaneously achieved, thus realizing a uniform plating during the target's sputtering while avoiding damage to the workpiece due to local high temperature.
