200908_LD_GlasgowBellBridgeSteel requires a very close control if the material is used in infrastructure(bridge wires, high building pillars) because of corrosion risks. Anti-corrosion treatment is mainly done with a huge quantity of hazardous chemicals. But recently scientists have found a way to replace these toxic chemicals, with an infrared light treatment that bonds new nanomaterials to steel, for a more durable coating.

The actual technology or is under the development of 3 companies: MesoCoat, Edison Materials Technology Center and Polythermics LLC. The 3 party has been granted their development by the U.S. Department of Commerce’s National Institute of Standards and Technology. This project will not only replace the usage of hazardous chemicals but will also reduce costs and increase the lifetime of steel infrastructure elements and maybe in the near future it will increase the lifetime of consumer products.

The actual anti-corrosion coatings are made with lead, cadmium, chromium and other toxic substances. When they start to wear down, another layer of volatile organic compound must be added before the new coating is applied. The toxic coatings can create serious heath problems to people. Metal corrosion is a huge problem for infrastructure, considering not only the polluting factor but as well the economical factor (only U.S. economy loses every year $276 billion due to metal corrosion).

The new process is much more simple: a nanocomposite metal-ceramic and polymer coating fusion with steel under infrared light. The protection offered is much more durable in time with no risk to health and with cheaper costs. Also the U.S. Air Force is testing a new nontoxic anti-corrosion material called PreKote to prevent aircraft corrosion.

    The newly invented infrared light treatment that bonds new nanomaterials to steel, for a more durable coating is very generic in idea as well as in full utility for preparing bridges and huge construction materials. Really thanks to the scientists who have endeavored their all tois to make their dream into a reality.
