The invention provides a method for the passivation of the surface of metal bands covered with a coating, particularly tin-coated steel bands (S), which move at a band speed (v) through a coating installation. To allow an efficient passivation of the metal band surface even at high band speeds and simultaneously the lubrication of the coated metal band surface, after the coating process has been completed, an aqueous solution of a surface active substance is sprayed onto the coated metal band that moves at band speed (v). The invention further provides a device for the application of a metal coating on a steel band, particularly in a band tin-coating installation, as well as to the use of substances for lubrication and/or passivation during the manufacture of tin-coated steel bands, which can be sprayed as an aqueous solution on the tin-coated steel band.
