Abstract
Procédé de détection et de mesure de la concentration efficace d'un constituant électroactif dans une solution de revêtement Il consiste à détecter la concentration d'un revêtement électroactif dans une solution de revêtement par mesure d'un courant électrolytique circulant entre une électrode d'indication et une électrode de référence ou une contre-électrode. Ces électrodes sont plongées dans la solution. L'électrode d'indication peut être réalisée dans un métal choisi dans le groupe comprenant le platine, l'or, l'iridium, l'osmium et le ruthénium ou un alliage de ces métaux. Elle est nettoyée périodiquement. Domaine d'application : revêtement de pièces métalliques.
