Abstract

L'invention concerne des bains galvanoplastie au chrome trivalent Ces bains sont constitués d'ions chrome trivalent dissous dans une solution aqueuse contenant un phosphite, qui peut également contenir un agent faiblement complexant, tel qu'un hypophosphite ou du glycocolle. L'invention s'applique en particulier au chromage électrolytique avec des électrolytes ayant de faibles teneurs en solides, sans effets fâcheux sur la vitesse de revêtement.
