Cathodic Protection Rectifiers

Everyone has seen the large-scale results of metal corrosion. The formation of rust or the cracking and flaking caused by brittleness are visible results of corrosion that can ruin property and require costly replacements. These changes in metal result from its interaction with substances in the immediate environment. Though water and salt are the most obvious culprits, corrosion can also be caused by industrial reactants such as acids and chlorides.

On the molecular level, the mechanism of corrosion is the switching of electrons from atoms of one substance to those of another. Oxygen steals electrons from other substances very easily, forming oxides that often have very different properties from the original substance...
