Abstract

Procedimiento para el pretratamiento de superficies metálicas que comprende las etapas a) fosfatizacion formadora de capa, b) postenjuague y c) laqueadoelectroforético catodico por inmersion, en el que, en la subetapa b), el postenluague se lleva a c abo con una solucion acuosa que contiene 0,001 g/l a 10 g/lde uno o varios de los cationes litio, cobre o plata, así como una sustancia conocida como acelerador en la fosfatizacion. El laqueado electroforético catodicopor inmersion de la etapa c) pue de llevarse a cabo con una laca electroforética catodica por inmersion con plomo convencional, o también, sin pérdidas, con unalaca electroforética por inmersion precipitable catodicamente moderna, exenta de plomo. En la etapa a) se fosfatiza con una solucion ácida que contiene Zn,presenta un valor de pH entre 2,5 y 3,6 con al menos uno de los siguientes aceleradores: m-nitrobencensulfonato, hidroxilamina, iones nitrobenzoato,p-nitrofenol, peroxido de hidrogeno, iones nitrilo, N-oxidos orgánicos , nitroguanidina, iones niquel. En la etapa b) la solucion acuosa contiene uno o variosaceleradores de fosfatizacion seleccionados entre: m-nitrobencensulfonato, hidroxilamina, iones, nitrobenzoato, p-nitrofenol, peroxido de hidrogeno, ionesnitrito, N-oxidos orgánicos, nitroguanidina, iones clorato.Method for the pretreatment of metal surfaces comprising steps a) layer forming phosphatization, b) post-rinse and c) cathode electrophoresic lacquered by immersion, in which, in the sub-stage b), the post-clumping is carried out with an aqueous solution containing 0.001 g / l to 10 g / l of one or more of the lithium, copper or silver cations, as well as a substance known as an accelerator in phosphatization. The cathode electrophoretic immersion lacquering of stage c) can be carried out with a cathode electrophoretic lacquer by conventional lead immersion, or also, without losses, with a cathode-free, lead-free, electrophoretic immersion lacquer. In step a) it is phosphatized with an acid solution containing Zn, it has a pH value between 2.5 and 3.6 with at least one of the following accelerators: m-nitrobenzenesulfonate, hydroxylamine, nitrobenzoate ions, p-nitrophenol, hydrogen peroxide, nitrile ions, organic N-oxides, nitroguanidine, nickel ions. In step b) the aqueous solution contains one or more phosphatization accelerators selected from: m-nitrobenzenesulfonate, hydroxylamine, ions, nitrobenzoate, p-nitrophenol, hydrogen peroxide, ions nitrite, organic N-oxides, nitroguanidine, chlorate ions.
