Abstract

Un procedimiento para la obtención electrolítica de capas oxídicas protectoras sobre aluminio y sus aleaciones en un electrolito que contienen sulfoácidos orgánicoscaracterizado porque como electrolito se emplean ácidos sulfónicos aromáticos que contienen oxi y/u oxo.A process for the electrolytic obtaining of protective oxide layers on aluminum and its alloys in an electrolyte containing organic sulfo acids characterized in that aromatic sulphonic acids containing oxy and / or oxo are used as electrolyte.
