Abstract

A method for preparing metal surfaces, in order to apply a protective coating, characterized by (a) contacting said metal surfaces with an aqueous solution containing at least about 1.0% w/v of an organic acid chosen from the group consisting of citric, gluconic, tartaric, oxalic, glycolic, tonic glycohex, malic, formic, acetic, ethylenediaminetetraacetic acids, and mixtures thereof, said aqueous solution of organic acid being adjusted with enough nitrogen base to provide a ph between 2.5 and 6, and an emulsifying composition containing a water-soluble organic solvent and a surfactant, until such metal surfaces substantially lack iron oxide scale and other foreign matters, and (b) adjust the ph of the solution to 5.5-7.5 by the addition of an oxidizing agent, and aerating until said metal surfaces are substantially free of magnetic etita (Machine-translation by Google Translate, not legally binding)
