Name any two metals used for electroplating
Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the … Zobacz więcej The electrolyte should contain positive ions (cations) of the metal to be deposited. These cations are reduced at the cathode to the metal in the zero valence state. For example, the electrolyte for copper plating can be a … Zobacz więcej It has been theorized that the first electroplating was done in Parthian Empire era. Wilhelm König was an assistant at the National Museum of Iraq Zobacz więcej The Haring–Blum cell is used to determine the macro throwing power of a plating bath. The cell consists of two parallel cathodes with a fixed anode in the middle. The cathodes … Zobacz więcej Electroplating changes the chemical, physical, and mechanical properties of the workpiece. An example of a chemical change is when nickel plating improves corrosion resistance. An example of a physical change is a change in the outward … Zobacz więcej There are a number of alternative processes to produce metallic coatings on solid substrates that do not involve electrolytic reduction: • Electroless deposition uses a bath containing metal ions and chemicals that will reduce … Zobacz więcej The Hull cell is a type of test cell used to semi-quantitatively check the condition of an electroplating bath.
