Abstract

The invention discloses a silver ornament surface brightness five-layer electroplating technology, and relates to silver electroplating technologies, in particular to a five-layer electroplating technology for silver ornaments with brightness surfaces. The technology includes the following five steps that 1, the silver ornaments are treated before electroplating; 2, the silver ornaments are electroplated; 3, palladium is electroplated on the silver ornaments; 4, platinum is electroplated on the silver ornaments; and 5, aftertreatment is conducted on the electroplated silver ornaments. The technology solves the problems that the silver ornaments are low in durability, prone to oxidation and the like due to a silver ornament surface three-layer electroplating method in the prior art.

Description

Technical field [0001] The invention relates to a silver electroplating process, in particular to a five-layer electroplating process of silver ornaments with bright surfaces. Background technique [0002] Silver is a precious metal with a long history of application. Its content in the earth's crust is very small, accounting for only 0.07ppm. Pure silver is a beautiful silver-white metal. Its jewelry and utensils have good reflectivity and can be polished. To achieve high brightness, it is widely used in jewelry and home decoration. And plating a layer of silver on some metal surfaces can also achieve the decorative effect of pure silver. It has a bright and delicate appearance, strong wear resistance, corrosion resistance, and discoloration resistance, so it has a wide range of applications. The non-bright silver plating process used in the past has poor appearance and low corrosion resistance, especially poor sulfur and discoloration resistance. In order to emit light, chemic...
