Title (EN) PROCESS FOR THE ANTICORROSION TREATMENT OF A SOLID METAL SUBSTRATE AND TREATED SOLID METAL SUBSTRATE CAPABLE OF BEING OBTAINED BY SUCH A PROCESS
(FR) PROCÉDÉ DE TRAITEMENT ANTICORROSION D'UN SUBSTRAT MÉTALLIQUE SOLIDE ET SUBSTRAT MÉTALLIQUE SOLIDE TRAITÉ SUSCEPTIBLE D'ÊTRE OBTENU PAR UN TEL PROCÉDÉ
Abstract: front page image
(EN)The invention relates to an anticorrosion treatment process in which applied to an oxidizable surface of a solid metal substrate is a liquid solution, referred to as treatment solution, comprising: at least one alkoxysilane, and at least one cerium (Ce) cation; in a liquid aqueous-alcoholic composition, said treatment solution being suitable for being able to form, at the surface of the solid metal substrate, a hybrid matrix by hydrolysis/condensation of each alkoxysilane(s) and of each cerium (Ce) cation; the treatment solution having a molar ratio (Si/Ce) of silicon element of the alkoxysilane(s) with respect to the cerium (Ce) cation(s) of between 50 and 500; characterized in that the cerium (Ce) cation(s) has(have) a concentration between 0.005 mol/L and 0.015 mol/L in the treatment solution.
(FR)L'invention concerne un procédé de traitement anticorrosion dans lequel on applique sur une surface oxydable d'un substrat métallique solide, une solution, dite solution de traitement, liquide comprenant : au moins un alcoxysilane, et au moins un cation du cérium (Ce); dans une composition hydro-alcoolique liquide, ladite solution de traitement étant adaptée pour pouvoir former en surface du substrat métallique solide, une matrice hybride par hydrolyse/condensation de chaque alcoxysilane(s) et de chaque cation de cérium (Ce); la solution de traitement présentant un rapport (Si/Ce) molaire d'élément silicium du(des) alcoxysilane(s) par rapport au(x) cation(s) du cérium (Ce) compris entre 50 et 500; caractérisé en ce que le(s) cation(s) du cérium (Ce) présente(nt) une concentration comprise entre 0,005 mole/L et 0,015 mole/L dans la solution de traitement.
