Nanocoat to detect metal corrosion

(This image of Metal Corrosion was taken with the PAXcam digital microscope camera made by MIS, Inc. on an Olympus metallograph at Battelle Advanced Materials Applications.)
Metalic corrosion is visible only after it has developed in the materials, but could not be detected before it initiates. Researchers report that nanotechnology has come to the help. A smart coating derived from the functional nanomaterial has been developed. This coating can be applied to a metal after the primer coating and before the final coat. Once corrosion initiates and corrosion product is generated from the metal, the nanocoat fluoresces indicating starting of decay. This technique will be invaluable for many industries because as any metal component/object begins to start corroding it can be immediately attended to before it can do any damage, may it be airplanes, containers, cars, machinery, bridges etc., The repair of metal can be done immediately and saving can be achieved in terms of time, energy, material and money. This smart coating can even be incorporated to the primer coating or integrated with the scanning device.
