Abstract

Procedure for obtaining a piece of silver and its alloys, or of silver-plated material, the surface of which has an increased resistance to corrosion, fogging and blackening and which, practically, retains with time and in the usual conditions, its Initial appearance again attractive and decorative, characterized by the fact that at least one metallic layer is deposited or applied on this piece, comprising at least one metal other than silver, capable of modifying the surface properties of the silver and by making it diffuse in the material of the piece.
