Brookhaven News: "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."
