ABSTRACT:
A method for pretreating the surfaces of electroconductive materials such as metals which are to be electroplated in an aprotic oxygen- and water-free organoaluminum electrolytic media in which the last mechanical operation generating fresh and bright surfaces is performed under the exclusion of air, oxygen, and moisture using a protective gas or protective liquid and the part being treated maintained in such an environment until electroplated.
