Title (DE) METALLISCHE GEGENSTÄNDE MIT GLASARTIGEN ODER GLASKERAMISCHEN PIGMENTIERTEN SCHUTZSCHICHTEN
(EN) METALLIC ARTICLES HAVING VITREOUS OR GLASS-CERAMIC PIGMENTED PROTECTIVE LAYERS
(FR) ARTICLES MÉTALLIQUES À COUCHES PROTECTRICES VITREUSES OU VITROCÉRAMIQUES PIGMENTÉES, À HAUTE RÉSISTANCE CHIMIQUE
Abstract:
(DE) Metallische Substrate mit einer glasartigen oder glaskeramischen pigmentierten Schutzschicht sind erhältlich durch Auftragen eines Alkalisilikat-haltigen Beschichtungssols auf das Substrat, oder eine Oberfläche davon und thermische Verdichtung der so erhaltenen Schicht, wobei das Alkalisilikat-haltige Beschichtungssol ein oxidisches Pigment mindestens eines Elementes, ausgewählt aus der dritten und vierten Haupt- oder Nebengruppe des Periodensystems der chemischen Elemente und den Übergangsmetallen Fe, Co, Ni, Cu, Zn, Nb und Ta, enthält.
(EN) Metallic substrates having a vitreous or glass-ceramic pigmented protective layer can be obtained by applying a coating sol containing an alkali metal silicate to the substrate or a surface thereof and thermal densification of the layer obtained in this way, where the coating sol containing alkali metal silicate contains an oxidic pigment derived from at least one element selected from the third and fourth main or transition groups of the Periodic Table of the chemical elements and the transition metals Fe, Co, Ni, Cu, Zn, Nb and Ta.
(FR) L'invention concerne des substrats métalliques à couche protectrice vitreuse ou vitrocéramique pigmentée, qui sont obtenus par application sur le substrat, ou sur une surface de ce substrat, d'un sol de revêtement renfermant un silicate alcalin, et densification thermique de la couche ainsi obtenue. L'invention est caractérisée en ce que le sol de revêtement renfermant le silicate alcalin renferme un pigment oxydant d'au moins un élément choisi dans le troisième et quatrième groupe principal ou sous-groupe du Système Périodique des éléments chimiques et parmi les métaux de transition Fe, Co, Ni, Cu, Zn, Nb et Ta.
