Abstract
Procedure for the obtaining of acid aqueous solutions for forming cinc phosphate coatings on metal surfaces. Is to combine between compounds that contain cinc, phosphate, chlorate, nitrit and complex fluoride, adding water. The solution of formed coatings has the next concentration of ions, in weight: of cinc, between 0.8 and 0.2 per 100; of phosphate, between 0.8 and 3 per 100, preferable between 0.8 and 0.1 per 100; of chlorate, between 0.05 and 0.35 per 100; of nitrit, between 0.001 and 0.1 per 100 and of complex fluoride, which is included within the relationship 0.4 and 0.63x0.0042, where <x> is the concentration of the ion of zinc in percentage in weight and <and> is the concentration of ion fluoride complex in percentage by weight, which preferably does not exceed 0.2%. Optionally in the coating solution can exist the nickel ion, with a concentration compared between 0, 3 and 0.8 per 100 in weight. For use in metal object coatings before painting to facilitate the adherence of the paint and improve the corrosión resistance. (Machine-translation by Google Translate, not legally binding)
