Scientists and engineers working to prolong the life of iron materials, especially in ocean going vessels, developed duplex corrosion protection. This technology prevented ionization (rusting), by using coatings, galvanization, and impressed current. The primary objective was to prevent the immediate electro chemical reaction between iron and moisture.
The results were impressive. By coating and enriching the metal to be protected with free electrons, the rusting process was successfully retarded. Modern electronic corrosion protection systems now have a wide variety of applications, from bridges to atomic power plants. The scientific community continues to find and improve applications of this technology. The Auto Saver System is a proven application of this technology.
