The present invention discloses a method for electroless plating of a metal or metal alloy onto a metal or a metal alloy structure comprising a metal such as molybdenum or titanium and alloys containing such metals. The method comprises the steps of activation, treatment in an aqueous solution comprising at least one nitrogen-containing compound or a hydroxy carboxylic acid and electroless plating of a metal or metal alloy. La présente invention a pour objet un procédé pour le placage anélectrolytique d'un métal ou d'un alliage métallique sur un métal ou une structure en alliage métallique comprenant un métal tel que le molybdène ou le titane et des alliages contenant de tels métaux. Le procédé comprend les étapes d'activation, de traitement dans une solution aqueuse comprenant au moins un composé contenant de l'azote ou un acide hydroxycarboxylique et de placage anélectrolytique d'un métal ou d'un alliage métallique.
