Substrates having an alloy finish and methods of producing the same. The finished product according to one embodiment of the present invention is a substrate having an alloy finish comprising two or more metals, and is made by the method of the present invention. Generally, the method of the present invention comprises provision of a substrate, electroplating two or more metals onto the substrate, and then baking the plated substrate to result an alloy of the plated metals through diffusion. Substrates made according to the present invention can be covered with a variety of types of alloy finishes, and a variety of characteristics of such finishes can be achieved. The method of the present invention uses steps of electroplating and heating that are well-known in the art, and does not require the use of toxic, cyanide-based plating baths.

L'invention concerne un substrat ayant une finition en alliage et ses procédés de production. Le produit fini selon un mode de réalisation de la présente invention est un substrat ayant une finition en alliage contenant au moins deux métaux, et est réalisé selon le procédé de la présente invention. Généralement, ce procédé consiste à prendre un substrat, à effectuer une électrodéposition d'au moins deux métaux sur le substrat puis à effectuer la cuisson du substrat plaqué pour obtenir un alliage des métaux plaqués par diffusion. Des substrats réalisés selon la présente invention peuvent être recouverts d'une variété de types de finitions d'alliages et on peut accomplir une variété de caractéristiques de ces finitions. Le procédé selon la présente invention utilise les étapes d'électrodéposition et de chauffage connues dans ce domaine, et rend superflue l'utilisation de bains galvanoplastiques toxiques à base de cyanure.
