What Kinds of Plating Baths are Used in Gold Electroplating? Gold and gold alloy plating is used in a wide variety of applications. Gold plating solutions can be classified into five general groups: alkaline gold cyanide, for gold and gold alloy plating; neutral cyanide gold, for high purity gold plating; acid gold cyanide, for bright hard gold and gold alloy plating; noncyanide (generally sulfite), for gold and gold plating; and miscellaneous. Alkaline gold cyanide plating baths contain potassium gold cyanide and potassium cyanide

Baths Used in Copper Electroplating Process Copper cyanide plating is widely used in many plating operations as a strike. However, its use for thick deposits is decreasing. For copper cyanide plating, cuprous cyanide must be complexed with either potassium or sodium to form soluble copper compounds in aqueous solutions. Copper cyanide plating baths typically contain copper cyanide and either potassium cyanide or sodium cyanide. Current densities range from 54 to 430 A/m2. Cathode efficiencies range from 30 to 60 percent. Ba

What is Brass Plating? Brass, which is an alloy of copper and uzinc, is the most widely used alloy electroplate. Brass plating primarily is used for decorative applications, but it is also used for engineering applications such as for plating steel wire cord for steel-belted radial tires. Although all of the alloys of copper and zinc can be plated, the brass alloy most often used includes 70 to 80 percent copper, with the balance zinc. Typical brass plating baths include 34 g/L of copper cyanide and 10 g/L of zinc cyanide. Oth

Advantages and Disadvantages of Trivalent Chromium Plating The advantages of the trivalent chromium processes over the hexavalent chromium process are fewer environmental concerns due to the lower toxicity of trivalent chromium, higher productivity, and lower operating costs. In the trivalent chromium process, hexavalent chromium is a plating bath contaminant. Therefore, the bath does not contain any appreciable amount of hexavalent chromium. The total chromium concentration of trivalent chromium solutions is approximately one-fift
