Scientists patent corrosion-resistant nano-coating for metals
Date:3/25/2009

UPTON, NY - Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a method for coating metal surfaces with an ultrathin film containing nanoparticles - particles measuring billionths of a meter - which renders the metal resistant to corrosion and eliminates the use of toxic chromium for this purpose. The scientists have been awarded U.S. Patent number 7,507,480 for their method and the corrosion-resistant metals made from it. The technology is available for licensing.

"Our coating is produced right on the metal using a simple two- or three-step process to produce a thin film structure by crosslinking among the component compounds," said chemist Toshifumi Sugama, a guest researcher at Brookhaven Lab. "The result is a layer less than 10 nanometers thick that protects the metal from corrosion, even in briny conditions."

Corrosion resistance is essential for metals used in a wide range of applications, from electronics to aviation to power plants. Traditionally, compounds containing a toxic form of chromium have provided the best corrosion resistance. Scientists looking to develop chromium-free alternatives have been unable to achieve the thin layers desirable for many applications. "Ultrathin coatings reduce the amount of material needed to provide corrosion resistance, thereby reducing the cost," Sugama explained.

Sugama's approach achieves several goals - low toxicity and excellent corrosion resistance in a film measuring less than 10 nanometers that can be applied to a wide array of metals, including aluminum, steel, nickel, zinc, copper, bronze, and brass. According to Sugama, the coating should be of specific interest to industries that produce coated valves, pumps, and other components, as well as the manufacturers of aluminum fins used in air-cooled condensers at geothermal power plants, where preventing brine-induced corrosion is a high priority.

The coating can be made in a variety
