(JA) 複層皮膜形成方法
要約
(EN)
The present invention addresses the problem of providing: a method for forming a multi-layered coating film, whereby it becomes possible to exert no influence on electrodeposition coatability even when a part or the entire of a water washing step is eliminated after a chemical conversion treatment and it also becomes possible to achieve excellent finish quality and corrosion resistance; and a coated article. The present invention provides a method for forming a multi-layered coating film, said method being characterized by comprising the steps of forming a chemical conversion coating film and an electrodeposition coating film on a metallic material of interest, i.e., step (1) of immersing the metallic material of interest in a chemical conversion treatment solution to form a chemical conversion treatment film and step (2) of eliminating a part or the entire of a water washing step and carrying out the electrodeposition coating of the metallic material of interest with a cation electrodeposition coating material to form the electrodeposition coating film. In the method, the content of sodium ions in the chemical conversion treatment solution is less than 500 ppm by mass.

Le problème à résoudre dans le cadre de la présente invention consiste à fournir : un procédé de formation d'un film de revêtement à plusieurs couches n'ayant aucune répercussion sur la capacité de revêtement par électrodéposition même quand tout ou partie d'une étape de lavage à l'eau est supprimé après un traitement par conversion chimique et permettant d'obtenir d'excellentes qualité de finition et résistance à la corrosion ; et un article pourvu d'un tel revêtement. La présente invention concerne donc un procédé de formation d'un film de revêtement à plusieurs couches. Ledit procédé est caractérisé en ce qu'il consiste à former un film de revêtement par conversion chimique et un film de revêtement par électrodéposition sur un matériau métallique présentant un intérêt, autrement dit ledit procédé comprend une étape (1) consistant à plonger le matériau métallique présentant un intérêt dans une solution de traitement par conversion chimique de façon à former un film à traitement par conversion chimique et une étape (2) consistant à supprimer tout ou partie d'une étape de lavage à l'eau et à effectuer le revêtement par électrodéposition du matériau métallique présentant un intérêt avec un matériau de revêtement par électrodéposition de cations de façon à former le film de revêtement par électrodéposition. Dans le procédé, la teneur en ions de sodium de la solution de traitement par conversion chimique est inférieure à 500 ppm en masse.
