A process for direct metal-plating of a plastic substrate (14). The process comprises the steps of: (i) activating a surface of modified polyolefin substrate to produce an active surface (16), the active surface (16) having at least about 7 % of carbon atoms in the form of carbonyl; (ii) electrochemically depositing metal layer (18) on the active surface (16).
L'invention concerne un procédé de galvanoplastie directe d'un substrat plastique (14). Ledit procédé consiste (i) à activer une surface d'un substrat polyoléfinique modifié afin d'obtenir une surface active (16), ladite surface active (16) comprenant au moins 7 % d'atomes de carbone sous forme de carbonyle, et (ii) à déposer par un procédé électrochimique une couche métallique (18) sur la surface active (16).
