In this podcast I very briefly summarized electroplating and how it is done. Basically, and electrolytic cell is used to break down an electrolytic solution, plating metal ions onto a negatively charged cathode. The flow of electrons causes the positive anode to break into ions and also cause some electrolytes to break down, forcing positive ions to bond to a negatively charged cathode forming a thin layer of metal on it. The main uses are to prevent corrosion, abrasion and other wear, and also for aesthetic purposes. It has been used since the 19th century. Electroplating is a good way to conserve precious metals by reducing the need to make entire objects out of them.
