Abstract:
(EN) A blackening phosphatizing agent, a metal member and a surface phosphatizing method thereof. The blackening phosphatizing agent is used for forming a film on the surface of a metal member. The black phosphatizing agent comprises, based on 1,000 parts by weight, the following components in parts by weight: 20-50 parts of phosphoric acid, 1-4 parts of nitrobenzenesulfonic acid sodium salt, 10-25 parts of zinc nitrate, 1-3 parts of citric acid, 2-10 parts of sodium tungstate, 0.1-1.0 parts of nickel nitrate, 5-10 parts of zinc oxide, and 0.5-2 parts of sodium fluoroborate, with the balance being water. The film layer formed by the blackening phosphatizing agent is densely crystallized, capable of blackening and brightening, and has good corrosion resistance and decorative properties.
(FR) L'invention concerne un agent de phosphatation de noircissement, un élément métallique et un procédé de phosphatation de surface correspondant. L'agent de phosphatation de noircissement est utilisé pour former un film sur la surface d'un élément métallique. L'agent de phosphatation de noircissement comprend, sur la base de 1 000 parties en poids, les constituants suivants en parties en poids : 20 à 50 parties d'acide phosphorique, 1 à 4 parties de sel de sodium d'acide nitrobenzènesulfonique, 10 à 25 parties de nitrate de zinc, 1 à 3 parties d'acide citrique, 2 à 10 parties de tungstate de sodium, 0,1 à 1,0 partie de nitrate de nickel, 5 à 10 parties d'oxyde de zinc et 0,5 à 2 parties de fluoroborate de sodium, le reste étant de l'eau. La couche de film formée par l'agent de phosphatation de noircissement est cristallisée de manière dense, apte au noircissement et à l'avivage, et présente une résistance à la corrosion et des propriétés décoratives satisfaisantes.
