What Is Involved in Silver Plating?

The earliest brightener carbon disulfide used in silver plating was proposed by Milword and Lyons in a patent issued in 1847. It is still in use today and has only been slightly changed. Silver plating is much cheaper than gold plating, and has high electrical conductivity, light reflectivity and chemical stability to organic acids and alkalis, so it has a much wider range of use than gold. In the early days, it was mainly used for decorations and tableware, and recently it has been increasingly used in aircraft and electronic products.

The silver-plated layer is easy to polish, has strong reflective ability and good thermal conductivity, electrical conductivity, and welding performance.

Silver plating first began in 1800, the first silver plating patent was issued by the British in 1838

In 1913, Frary reported

The coating is used to prevent corrosion and increase

It has good electrical conductivity and a bright and shiny surface, and the silver layer has high corrosion resistance. Because of these advantages, silver-plated wires have become the first choice for high-frequency wires and colored textile threads.

Silver tarnishes very quickly in most air. This discoloration is a black-out sulfide stain which not only pumps the appearance but also loses solderability. In order to prevent or delay the formation of this transition bar, silver plating needs post-plating treatment such as overlaying gold or rhodium. Passivation treatments include chromating and coating. Oxidation plating (beryllium), colloidal ( ¹⁾ .
