Abstract:

(EN)A visible colored chromium- and phosphorus-free conversion coating can be formed on a metal surface by contacting it with an aqueous liquid composition that comprises an alizarine dye and a product of chemical interaction between a first initial reagent component selected from the group consisting of fluoroacids of the elements titanium, zirconium, hafnium, boron, aluminum, silicon, germanium, and tin; and a second initial reagent component selected from the group consisting of titanium, zirconium, hafnium, boron, aluminum, silicon, germanium, and tin and all of oxides, hydroxides, and carbonates of all of titanium, zirconium, hafnium, boron, aluminum, silicon, germanium, and tin.
(FR)Une couche de conversion visible colorée exempte de chrome et de phosphore peut être formée sur une surface métallique par mise en contact de ladite surface avec une composition aqueuse liquide qui comprend un colorant d'alizarine et un produit d'interaction chimique entre un premier réactif initial choisi dans le groupe constitué de fluoroacides des éléments titane, zirconium, hafnium, bore, aluminium, silicium, germanium et étain, et un second réactif initial choisi dans le groupe constitué de titane, zirconium, hafnium, bore, aluminium, silicium, germanium et étain et de tous les oxydes, hydroxydes et carbonates de tous les éléments du groupe constitué de titane, zirconium, hafnium, bore, aluminium, silicium, germanium et étain.
