To obtain the best qualities that iron has to offer like high ductility, more corrosion resistance, and better magnetic characteristics; a chemical process must occur to remove impurities.
Electrolytic iron is considered the “wet process” since electrolysis requires electric charges to move through a liquid solution.
An anode (raw material) and a cathode (base plate) are immersed into an electrolyte including iron ions and other components.
ESR (electro-slag remelting) method is a process of dripping the molten metal refining pure iron as an electrode.
Landing gear, engine shafts in jet aircraft, and gas turbines of generators, are areas that require the use of electrolytic iron.
