A metal member is manufactured that has a plating layer of precious metal on the surface of a bare metal portion formed of a predetermined metal. First, a surface layer of the bare metal portion is removed. Then, a plating of precious metal is applied to the portion where the surface layer of the bare metal portion was removed. Then, the metal member is heat treated in an inert atmosphere. As a result, a metal member can be manufactured that has less carbide and hydrogen near a boundary surface of the plating layer and the bare metal portion than it would if the removing step and the heat treating step were not performed. With a metal member manufactured in this way, the plating layer does not easily peel away.
L'invention concerne un élément métallique manufacturé présentant une couche de placage en métal précieux appliquée sur la surface d'une partie métallique nue constituée d'un métal prédéterminé. L'invention concerne également un procédé de fabrication de cet élément dans lequel on retire une couche de surface de la partie métallique nue, puis on applique un placage de métal précieux sur la partie où l'on a retiré la couche de surface de la partie métallique nue, ensuite on applique un traitement thermique à l'élément métallique dans une atmosphère inerte. Ainsi, on peut fabriquer un élément métallique comportant moins de carbure et d'hydrogène près d'une surface limitrophe séparant la couche de placage et la partie métallique nue que dans le cas où l'on supprime l'étape de retrait et l'étape de traitement thermique. Grâce à un tel procédé de fabrication, la couche de placage présente une bonne résistance à l'écaillage.
