Gold plating - Wikipedia

Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating This article covers plating methods used in the modern electronics industry; for more traditional methods, often used for much larger objects, see gilding Gold Plating - an overview | ScienceDirect Topics,516 Potassium Gold Cyanide and Potassium Stannate These two compounds are examples of the electrochemical production of electroplating chemicals Potassium gold cyanide is the most important gold plating chemical Almost all the gold used for contacts in the electronic industry is derived from potassium gold cyanideGold Touch Inc Cyanide free gold plating solutions and ,We manufacture the Tivian™ brand complete line of cyanide free gold plating solutions and conductive paints that are ideal for jewelers and other platers concerned about using cyanide Tivian non cyanide gold solutions have been used by as the top cyanide-free solutions for more than twenty years
