Abstract

L'INVENTION EST RELATIVE A DES SOLUTIONS POUR LE REVETEMENT DE METAUX. DES SURFACES METALLIQUES, TELLES QUE DES SURFACES AYANT SUBI UN ZINGAGE, SONT TRAITEES PAR UNE SOLUTION NON TOXIQUE CONSTITUEE D'ACIDE SULFURIQUE, DE PEROXYDE D'HYDROGENE ET D'UN SILICATE, AVEC EVENTUELLEMENT DES ADDITIFS SUPPLEMENTAIRES CONSTITUES PAR DES COMPOSES ORGANIQUES DU PHOSPHORE ET DES COMPOSES ORGANIQUES DE L'AZOTE. UN TRAITEMENT DE SURFACES METALLIQUES PAR CES SOLUTIONS AMELIORE LE BRILLANT ET AUGMENTE LA RESISTANCE A LA CORROSION.THE INVENTION RELATES TO SOLUTIONS FOR THE COATING OF METALS. METAL SURFACES, SUCH AS ZINC PLATED SURFACES, ARE TREATED WITH A NON-TOXIC SOLUTION CONSISTING OF SULFURIC ACID, HYDROGEN PEROXIDE AND A SILICATE, WITH POSSIBLE ADDITIONAL ADDITIVES CONSTITUTED BY PHOSPHORUS AND ORGANIC COMPOUNDS ORGANIC COMPOUNDS OF NITROGEN. TREATMENT OF METAL SURFACES USING THESE SOLUTIONS IMPROVES THE GLOSS AND INCREASES THE CORROSION RESISTANCE.
