| description | The present invention relates to a process for the anti-corrosion pre-treatment of a multiplicity of components in series, wherein each component in the series at least partly has surfaces of zinc and undergoes successive process steps for the deposition of iron and for zinc phosphatizing. In the process step for the deposition of iron, the layer add-on to be established is at least 10 milligrams of elemental iron per square meter of the zinc surfaces. The zinc phosphatizing subsequent to this deposition of iron takes place by means of an acidic aqueous composition which as well as zinc ions, phosphate ions and free fluoride also comprises a particulate constituent which is in dispersion in water and which is at least partly composed of hopeite, phosphophyllite, scholzite and/or hureaulite, and is provided by means of an aqueous dispersion of these crystalline solids that is stabilized with at least one polymeric organic compound.
La presente invención se refiere a un proceso para el pretratamiento anti-corrosión de una multiplicidad de componentes en serie, en donde cada componente en la serie al menos tiene parcialmente superficies de zinc y se somete a etapas del proceso sucesivos para la deposición de hierro y para la fosfatación de zinc. En la etapa del proceso para la deposición de hierro, la capa de recubrimiento que será establecida es al menos 10 miligramos de hierro elemental por metro cuadrado de las superficies de zinc. La fosfatación de zinc subsecuente a esta deposición de hierro toma lugar por medio de una composición acuosa acídica la cual además de los iones de zinc, iones de fosfato y fluoruro libre también comprende un constituyente particulado dispersado en el agua el cual es al menos parcialmente compuesto de hopeíta, fosfofilita, scholzita y/o hureaulita, y se proporciona por medio de una dispersión acuosa de estos sólidos cristalinos que se estabiliza con al menos un compuesto orgánico polimérico. |
