tha 4-A differential aeration cell,corrosion take place from electrode being thoroughly aerated to another de aerated. 5-Selective Leaching corrosion based on the more electrochemical component of an alloy is usually the element that is removed. 6-Electrolytic Cells are Non-spontaneous redox reactions and convert the chemical energy to electric energy.
