Abstract
Procedimiento para el pretratamiento de superficies de acero galvanizadas con zinc, caracterizado por que las superficies de acero galvanizadas con zinc ii) se ponen en contacto con una composición alcalina con un valor de pH de al menos 8,5 que contiene a) al menos 0,01 g/l de iones de hierro, b) uno o varios ácidos carboxílicos orgánicos solubles en agua, que presentan al menos un grupo amino en posición α, β o γ con respecto al grupo ácido, así como sus sales solubles en agua, c) uno o varios oxoácidos de fósforo o nitrógeno así como sus sales solubles en agua, estando presente al menos un átomo de fósforo o un átomo de nitrógeno en un estado de oxidación medio y iii) a continuación se ponen en contacto, para el tratamiento de conversión de química húmeda de pasivación, con una composición acuosa ácida que presenta un valor de pH en el intervalo de 2,5-3,6 y que contiene a) de 0,2 a 3,0 g/l de iones de zinc (II), b) de 5,0 a 30 g/l de iones de fosfato calculado como P2O5 y c) en cada caso menos de 0,1 g/l de compuestos iónicos de los metales níquel y cobalto, en cada caso con respecto al elemento metálico.

modo de aplicación, debido a la ferrización auto-limitante por medio de las composiciones alcalinas no se logran películas de capa de hierro ostensiblemente por encima de 300 mg/m2 respecto del elemento hierro.
Para una formación suficiente de capas y una protección óptima de los cantos durante el tratamiento de las superficies de acero galvanizadas con zinc, inmediatamente después de la ferrización en la etapa ii), con o sin etapa de enjuague posterior, deberían estar presentes realizadas películas de capa de hierro de preferentemente al menos 20 mg/m2, de modo particularmente preferido al menos 50 mg/m2, de modo especialmente preferido más de 100 mg/m2 pero preferentemente no más de 250 mg/m2, en cada caso con respecto al elemento hierro.
La película de capa de hierro sobre las superficies de zinc puede determinarse después de disolución del recubrimiento por medio de un procedimiento espectroscópico, que se describe en la sección de ejemplos de la presente invención.
La ferrización en la etapa ii) del procedimiento de acuerdo con la invención se realiza preferentemente sin corriente externa, es decir sin aplicar una fuente de tensión externa en el componente metálico.
En la etapa iii) del procedimiento de acuerdo con la invención, después de la etapa ii), se efectúa con o sin una etapa de enjuague intermedia como tratamiento de conversión de química húmeda de pasivación una fosfatación con zinc, en cuyo caso en la fosfatación con zinc es posible prescindir en gran medida de la presencia de los metales pesados Ni y/o Cu debido a la ferrización previa de las superficies de zinc del componente metálico en la etapa ii). Para una posterior fosfatación con zinc, la ferrización de las superficies de zinc produce entonces la ventaja inesperada de que para superficies de zinc fosfatadas de esta manera resulta una protección anticorrosiva y una adherencia de pintura que es comparable con la fosfatación con zinc de superficies de hierro o de acero.
Los componentes metálicos pretratados que presentan superficies de zinc y que provienen directamente de un procedimiento según la invención, luego son dotados preferentemente con una capa de cubrimiento orgánica, con o sin etapa intermedia de enjuague y/o secado. La primera capa de cubrimiento en el pretratamiento de elementos estructurales ya cortados, conformados y unidos es habitualmente una pintura de aplicación electroforética por inmersión, de modo particularmente preferido una pintura de inmersión catódica. Por lo contrario, después del procedimiento según la invención se aplican recubrimientos orgánicos de imprimación preferentemente como primera capa de cubrimiento orgánica en el caso del recubrimiento anticorrosivo o decorativo de fleje de acero galvanizado con zinc.
Los componentes metálicos tratados en un procedimiento de acuerdo con la invención, los cuales presentan superficies de zinc, se utilizan en la construcción de carrocerías durante la fabricación de automóviles, en construcción de barcos, en el ramo de la construcción así como para la fabricación de electrodomésticos.
Ejemplos de realización:
La influencia de diferentes α-aminoácidos en cuanto a la homogeneidad de la ferrización después de poner en contacto las composiciones alcalinas con acero electrolíticamente galvanizado con zinc mediante inmersión se refleja en la tabla 1.
Primero, con todas las composiciones (C1-C4) se obtienen revestimientos delgados de hierro oxídico y/o metálico sobre las superficies de zinc ("ferrización"), formándose sin embargo recubrimientos particularmente homogéneos especialmente de las composiciones (C1; C5) que contienen glicina.
