Abstract

The invention provides an electroplating anti-black method of silver ornament. The electroplating anti-black method of silver decoration comprises the following steps that a layer of silver is electroplated on the surface of a silver ornament, and a silver electroplating layer is formed; a layer of palladium is electroplated on the surface of the silver ornament forming the silver electroplating layer to form a palladium electroplating layer; a gold layer is electroplated on the surface of the silver ornament forming the palladium electroplating layer to form a gold electroplating layer, or arhodium layer is electroplated on the surface of the silver ornament forming the palladium electroplating layer to form a gold electroplating layer; and a layer of nano protective layer is electroplated on the surface of the silver ornament forming the gold electroplating layer or the rhodium electroplating layer. The method has the beneficial effects that the silver protection layer, the palladium protection layer, the gold protection layer or the rhodium protection layer and the nano protection layer are electroplated on the silver ornament in sequence, it is guaranteed that the silver ornament is not easy to oxidize in a wearing process, so that the occurrence of blackening conditions of the silver ornament can be avoided.
