Abstract
Procédé pour appliquer un revêtement par déposition électrochimique sur un support métallique faisant fonction d'anode dans une cellule électrochimique par passage du courant continu de la cathode à l'anode dans un électrolyte liquide alcalin contenant au moins un monomère phénolique, avec formation progressive d'une pellicule adhérente et imperméable d'une résine polymère phénolique. Le solvant utilisé est l'eau et/ou un alcool, le monomère phénolique consistant en phénol non substitué en quantité de 0 à 250 g/l d'électrolyte, et au moins un phénol portant des substituants halogéno, alcoxy ou alkyle en quantité totale de 5 à 35 g/l d'électrolyte, les substituants se trouvant dans les positions ortho ou méta et non para; la substance basique est une alkylènediamine éventuellement disubstituée par des groupes hydroxyalkyle sur les deux atomes d'azote, en quantité de 1 à 0 % du volume de l'électrolyte, et la densité de courant continu ne dépasse pas 10 mA/cm**2 du support métallique. Le procédé selon l'invention permet d'obtenir avec de faibles consommations de courant des pellicules imperméables et adhérentes pouvant atteindre de 25 à 30 mu .
