Title (EN) METHOD FOR ELECTROLESS PLATING OF A PRECIOUS METAL
(FR) PROCÉDÉ DE DÉPÔT AUTOCATALYTIQUE D'UN MÉTAL PRÉCIEUX
Abstract: front page image
(EN)Process for forming a precious metal layer (5) on a surface of a substrate (1) comprising steps of: providing a substrate (1); activation of a surface of said substrate (1) by wetting the said surface with a suspension (2) of precious metal nanoparticles (3) in a solvent so as to deposit precious metal nanoparticles (3) thereupon, said solvent comprising at least one organic solvent; immersion of the thus-activated surface in an aqueous solution (4) comprising at least one precious metal salt so as to deposit a precious metal layer (5) on the said surface.
(FR)Cette invention concerne un procédé de formation d'une couche de métal précieux (5) sur une surface d'un substrat (1), comprenant les étapes consistant à : utiliser un substrat (1) ; activer une surface dudit substrat (1) par mouillage de ladite surface avec une suspension (2) de nanoparticules de métal précieux (3) dans un solvant de façon à déposer des nanoparticules de métal précieux (3) sur celle-ci, ledit solvant comprenant au moins un solvant organique ; immerger la surface activée dans une solution aqueuse (4) comprenant au moins un sel de métal précieux, de façon à déposer une couche de métal précieux (5) sur ladite surface.
