Corrosion & Corrosion Resistance
www.fastenal.comConcentration-cell and pitting corrosion contrast with galvanic corrosion in that concentration-cell and pitting require only one metal in the presence of an electrolyte to set up an attack system. This type of corrosion begins with the creation of a differential in concentration of oxygen at the metal surface (an enclosed bubble of air).

Chapter 21: ELECTROCHEMISTRY TYING IT ALL TOGETHER
laude.cm.utexas.edu6. Galvanic Cell and Electrolytic Cels. There are two kinds of electrochemical cells, those that occur spontaneously and those that require work to occur. This is simply the consequence of having reactions that are: spontaneous ( ∆ G < 0 is a battery or a galvanic cell) and reactions that are non spontaneous ( ∆ G> 0 is an electrolytic cell)
