How insoluble titanium anodes used in nickel plating baths? During nickel plating, the anode provides electrical contact with the solution and distributes the current to the work being plated. In most cases, the plate uses nickel metal anodes which dissolve as the current flows and thereby replace the nickel ions discharged at the cathode, maintaining the concentration of nickel salts dissolved in the plating solution. Small insoluble anodes made by titanium with a thin coating of platinum have been used to increase the current

Applications for Nickel Plating The nickel plating process is used extensively for decorative, engineering, and electroforming purposes because the appearance and other properties of electrodeposited nickel can be varied over wide ranges by controlling the composition and the operating parameters of the plating solution. Decorative applications account for about 80% of the nickel consumed in plating; 20% is consumed for engineering and electroforming purposes. Decorative nickel plating solutions contain organic additives that mo

Different Methods for Zinc Electroplating Process Zinc electroplating of parts of fixed dimensions is carried out by different methods of handling - barrel and rack plating. In barrel plating, parts are handled in bulk, while in the rack method, pieces are handled separately by attaching them to a conducting fixture in the form of a wire, hook, or clip. In practice bolts, nuts, nails, screws, washers and small articles in general are commonly zinc plated by the barrel method. After the perforated barrel, which is made of no

What is Electro galvanizing of Strip Steel The electrolyte now employed for electrogalvanizing of strip steel lines in use is composed of zinc sulfate, sodium sulfate, magnesium sulfate, and sulfuric acid. The magnesium sulfate imparts luster to the plated surface, while the sodium sulfate acts as a conducting salt. The solutions are nearly always of the acid type using zinc sulfate or zinc chloride plus other salts to improve conductivity. However, each uses its own particular type of solution, including cyanide electrolytes. T
