Abstract

Un procédé de placage consiste à : obtenir une solution de placage contenant du nickel ; immerger un substrat métallique dans la solution de placage ; et appliquer une tension entre le substrat et une anode afin d'appliquer un placage. L'obtention consiste à mélanger de la poudre de chrome avec un précurseur de la solution de placage de sorte que la solution de placage est une solution de placage contenant du Cr. Le placage tel qu'appliqué forme une couche contenant des particules de chrome à partir de la poudre.
