Abstract

La invención hace referencia a un proceso para el pretratamiento de piezas que tienen una superficie de aluminio o aleaciones de aluminio para la formación sin corte y/o el enlace mediante soldadura o unión adhesiva a piezas pretratadas de manera similar o de manera opcional, en su caso, recubiertas previamente, o de manera opcional, a partes recubiertas previamente compuestas por acero y/o acero galvanizado y/o galvanizado con aleaciones, y también para un posterior tratamiento contra la corrosión permanente mediante fosfatación, a través de un tratamiento de conversión libre de cromo, mediante la aplicación de un imprimador o mediante recubrimiento de superficie, caracterizado porque las piezas a) se decapan mediante una solución ácida acuosa que comprende un ácido mineral por inmersión o pulverización, b) se enjuagan con agua y c) se ponen en contacto con una solución ácida acuosa libre de cromo y que comprende Zr como fluoruro complejo y Mo como molibdato en una relación en peso (que se calcula como metal de Zr/Mo) de Zr:Mo de 15:1 a 3.5:1 mediante la aplicación por inmersión o pulverización para generar, luego del secado posterior, un peso de la capa de, en cada caso, 2 a 15 mg/m2 de Zr y Mo, donde la solución comprende de 100 a 800 mg/l de Zr y de 30 a 100 mg/l de Mo (que se calcula como metal de Zr/Mo) y tiene un pH de 2,5 a 4,5.The invention refers to a process for the pretreatment of parts having an aluminum surface or aluminum alloys for the formation without cutting and / or the bonding by welding or adhesive bonding to similarly or optionally pretreated parts, in their case, previously coated, or optionally, to previously coated parts composed of steel and / or galvanized and / or galvanized steel with alloys, and also for a subsequent treatment against permanent corrosion by phosphating, through a free conversion treatment of chromium, by applying a primer or by surface coating, characterized in that the pieces a) are stripped by an aqueous acidic solution comprising a mineral acid by immersion or spraying, b) rinsed with water and c) contacted with a chrome-free aqueous acid solution comprising Zr as a complex fluoride and Mo as a molybdate in a rel ation by weight (calculated as Zr / Mo metal) of Zr: Mo from 15: 1 to 3.5: 1 by immersion or spraying to generate, after subsequent drying, a layer weight of, in each case, 2 to 15 mg / m2 of Zr and Mo, where the solution comprises 100 to 800 mg / l of Zr and 30 to 100 mg / l of Mo (calculated as Zr / Mo metal) and has a pH 2.5 to 4.5.
