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.
