Abstract
L'INVENTION EST RELATIVE A DES SOLUTIONS PERMETTANT LE REVETEMENT DE SURFACES METALLIQUES. ON TRAITE DES SURFACES METALLIQUES PAR UNE SOLUTION NON TOXIQUE CONSTITUEE D'ACIDE SULFURIQUE, DE PEROXYDE D'HYDROGENE, D'UN SILICATE, D'UN ACTIVEUR PRIMAIRE FORME PAR UN COMPOSE ORGANIQUE DE PHOSPHORE ET D'AU MOINS UN ACTIVEUR SECONDAIRE CHOISI PARMI L'ACIDE ASCORBIQUE, L'ACIDE BORIQUE, L'ACIDE GLUCONIQUE, L'ACIDE GLYCOLIQUE, L'ACIDE TARTRIQUE ET LEURS SELS. LES REVETEMENTS SUIVANT L'INVENTION DONNENT AUX SURFACES METALLIQUES UN BRILLANT AMELIORE ET UNE MEILLEURE RESISTANCE A LA CORROSION.
