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

What is the Decorative Chromium Electroplating Process? Decorative chromium electroplating is applied to metals and plastics. In decorative plating of metals, the base material generally is plated with layers of copper and nickel followed by a relatively thin layer of chromium to provide a bright surface with wear and tarnish resistance. Decorative plating is used for items such as automotive trim, metal furniture, bicycles, hand tools, and plumbing fixtures. The decorative chromium electroplating process consists of pretreatmen
