Electroplating is an electrodeposition process that involves coating a surface with a metal by means of an electric current. Several materials are used for electroplating including copper, nickel, gold, silver and zinc. This process is used to create elements that conduct a larger current such as a micro electrical coil. Electroplating can be applied to deposit relatively thick films of magnetic material to create a larger magnetic force. This mechanism is commonly used in magnetic separation or magnetic force-based actuators. Electroplating can be classified into several types depending on the materials used such as copper plating, silver plating, zinc plating and gold plating. Copper plating is extensively used to prevent case hardening of steel on specified parts. Silver plating is done on tableware, engine bearings and electrical contacts. The most prominent use of gold plating is on jewelry and watch cases. The corrosion of steel articles can be prevented by zinc coatings. The objective of this book is to give a general view of electroplating and its applications. It will provide comprehensive knowledge to all the readers.
