Abstract

Process for the formation of manganese phosphate coatings on thin iron and steel, with fine granulation and very adherent, using solutions of acid manganese phosphate containing oxidation agents, characterized in that the surfaces to be treated are put in contact with a solution in which the free P2O5: total P2O5 ratio is adjusted and maintained between 0.35 and 0.55, preferably between 0.40 and 0.50.
