Abstract :
Electrolytic action is BY no means new or unfamiliar. It is as old as electricity itself and has been evidenced in many ways throughout the entire application and use of electricity. One of the early applications of electrolytic action pertaining to metals was employed in the refining of copper and similar metals. Also, electrolytic action was employed in the plating of metals on surfaces requiring a high finish or protective coating, which, of necessity, should be very thin. This application is best evidenced in nickel plating and chromium plating which has been widely used for a number of years.
