Abstract
(EN)
A metallic material having on the surface thereof a surface treatment coating film which, in the uncoated state or after having been coated, is equal or superior in corrosion resistance to coating films formed by the zinc phosphate treatment or chromate treatment as a conventional technique. The coating film generates no sludge, contains no ingredients harmful to the environment, and is formed from ingredients capable of being deposited by a simple method. It is a surface-treated metallic material comprising a metallic material which has on the surface thereof a surface treatment coating film layer comprising the following ingredients (A) and (B): (A) an oxide and/or hydroxide of at least one metallic element selected from the group consisting of Ti, Zr, and Hf and (B) an Al element. In the surface treatment coating film layer, the mass ratio of the deposition amount, B, of the Al element of the ingredient (B) to the total deposition amount, A, of the metallic elements of the ingredient (A), K1=B/A, is 0.001≤K1≤2.

L'invention se rapporte à une matière métallique dont la surface porte un film protecteur de traitement superficiel qui, dans l'état non enduit ou après l'enduction, présente une résistance à la corrosion supérieure ou égale à celle des films protecteurs formés par une technique conventionnelle de traitement au phosphate de zinc ou par chromatation. Le film protecteur ne génère pas de boues, il ne contient pas d'ingrédients nocifs pour environnement et il est formé à partir d'ingrédients qui peuvent être déposés par un procédé simple. La matière métallique à traitement superficiel de l’invention comprend une matière métallique dont la surface porte un film protecteur de traitement superficiel comprenant les ingrédients (A) et (B) suivants : (A) oxyde et/ou hydroxyde d'au moins un élément métallique choisi dans le groupe composé de Ti, Zr et Hf et (B) élément Al. Dans le film protecteur de traitement superficiel, le rapport entre la masse de la quantité déposée, B, de l'élément Al de l'ingrédient (B) et celle de la quantité déposée totale, A, des éléments métalliques de l'ingrédient (A), K1 = B/A, est tel que 0,001 ≤ K1 ≤ 2.
