Abstract
Rapid process of degreasing and amorphous phosphating of ferrous metal surfaces, characterized in that the pieces to be treated are passed, only, through two acid aqueous baths, a first bath of degreasing and prefostasis, containing, for every 1000 parts by weight of water , from 5 to 15 parts by weight of nonionic surfactant, from 0.1 to 5 parts by weight of 75% orthophosphoric acid and from 1 to 5 parts by weight of sodium acid pyrophosphate, in addition to a second phosphating bath , which simultaneously ends with the degreasing process, and which contains, for every 1000 parts by weight in water, from 0.1 to 5 parts by weight of nonionic surfactant, from 0.1 to 5 parts by weight of 75% orthophosphoric acid and 0.1 to 1 parts of sodium acid pyrophosphate, without intermediate or final washing; the pH of the baths being comprised between 3 and 6, its temperature being constant and between 60 and 85º C, the duration of immersion in each bath varying between 20 seconds and 2 minutes and ensuring agitation of the baths.
