Abstract
L'invention concerne un agent passivant, une pièce métallique et un procédé de traitement de passivation s'y rapportant. L'agent passivant est utilisé pour le prétraitement de surface de la pièce métallique. Sur une base de 100 parties en poids, l'agent passivant comprend les constituants suivants, en teneurs massiques : 0,2 g/L à 4 g/L de nitrate céreux, 0,01 g/L à 0,3 g/L de borax, 0,01 g/L à 0,1 g/L de bifluorure d'ammonium, 3 g/L à 20 g/L d'acide phytique et 0,01 g/L à 0,3 g/L de fluorure nickélifère. Aucun constituant contenant du chrome n'est utilisé dans l'agent passivant, de sorte que l'agent passivant soit un agent passivant sans chrome et soit approprié pour un traitement de passivation de la pièce métallique. Une fois le traitement effectué à l'aide de l'agent passivant, une couche de passivation résistante à la corrosion, de teinte incolore à faiblement colorée, est formée. Le produit ne contient pas d'ions chrome dangereux pour l'environnement ; il est utilisé pour fournir une couche inférieure pour un traitement de revêtement et un traitement de protection, et il constitue un produit écologique et respectueux de l'environnement. Lorsque la pièce traitée est en alliage de magnésium, la valeur de pH est ajustée à 5 à 6 à l'aide d'eau ammoniacale.
