Definitions

  • nitrite, chlorate and fluoride ions are also added to the bath in the form of the sodium salts; the fluoride ions optionally also in the form of fluorosilicic acid and / or fluoroboric acid.
  • the sodium salt of 3-nitrobenzenesulfonic acid is used as the preferred organic nitro compound, and hydrogen peroxide is used as the preferred peroxo compound.
  • Phosphoric acid serves as the source of the phosphate ions.
  • the pH of the bath is adjusted to the desired value by adding aqueous sodium hydroxide solution.

Abstract

Un procédé permet de revêtir avec du phosphate des surfaces métalliques, notamment en fer, acier, zinc, alliages de zinc/nickel, aluminium et/ou ses alliages ou en matériaux composites d'aluminium et d'acier, par pulvérisation, pulvérisation et immersion et/ou immersion, avec une solution aqueuse contenant entre 0,01 et 5 g/l d'ions de zinc(II), entre 0,3 et 10 g/l d'ions de barium(II), entre 3 et 50 g/l d'ions de phosphate, entre 0 et 2 g/l d'ions de fluorure, et en tant qu'accélérateurs, entre 0,5 et 30 g/l d'ions de nitrite et/ou entre 0,01 et 1 g/l d'ions de nitrite et/ou entre 0,2 et 10 g/l d'ions de chlorate et/ou entre 0,1 et 2 g/l d'un composé nitro-organique et/ou entre 0,01 et 5 g/l d'un composé peroxyde. Le pH de la solution est ajusté pour se situer entre 2 et 4.
