When discussing electroplating and understanding how the technology works there is often a reference to Faraday’s Law of Electrolysis.
“Faraday’s Law of Electrolysis” says that one Faraday of electricity (96,487 ampere-seconds) will electro-deposit one gram molecular weight of metal on the cathode. Therefore, knowing the surface area of the part, density of the plated metal, efficiency of the plating bath and desired average thickness of the plating, you can calculate the required ampere seconds to deposit this thickness very accurately.
Sheffield Platers utilizes two types of metal finishing, Electrolytic plating, which utilizes “Faradays Law” and Electroless plating. Below are two brief descriptions of Electrolytic and Electroless plating.
