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

How Soluble Anodes Used in Zinc Electroplating?  Anodes used for electroplating zinc are of two types - soluble and insoluble. The soluble anodes are obviously zinc to provide the metal to be plated. With insoluble anodes, the zinc is furnished to the electrolyte by leaching material containing zinc oxide. In the electroplating of zinc with soluble anodes, the zinc ions in the electrolyte are maintained during operations by the electrolytic dissolution of the zinc of which the anodes are comprised. The plating or electrogal

Alkaline and Acid Plating Solutions Used for Zinc Plating Process These are two general plating baths types: one utilizes an acid electrolyte and the other an alkaline electrolyte. The former is known as sulfate, sulfate-chloride, chloride, chloride-acetate, and fluoborate baths, depending upon their chief constituents. The alkaline electrolytes are mostly cyanide baths, although zincate and pyrophosphate baths also have their advocates. The choice between the types used is based upon a number of factors. For instance, in consid
