Native Anti-corrosion Coatings for Metals

Summary The need: Corrosion of metals hamper the performance and safety of products ranging from medical implants to large-scale naval vessels, aircraft, bridges, and oil pipeline structures. A 2002 study of the US Federal Highway Administration estimated the cost of corrosion of metallic materials to be $276 billion, approximately 3.1% of national Gross Domestic Product (GDP). Developing novel approaches to mitigate corrosion is of great scientific and technological importance.

Applications Our solution: A new technology from Harvard synthesizes nanoscale coatings on the surfaces of metals to achieve superior corrosion resistance on surfaces ranging from nanoscale materials to large-scale engineering structures as well as aircraft and naval vessels. We have developed easy-to-adopt, cost-effective techniques for 1) forming an oxide coating on a metal surface to provide corrosion resistance to the metal; 2) improving the corrosion resistance of pre-existing oxide coatings on metal or alloy surfaces; and 3) creating corrosion resistant metal oxide coatings on metal surfaces immersed in water, such as ships (in which case the technique may be applied while the ship is in water to repair / improve the quality of existing passive oxide surfaces). The technology is scalable, may not require high-vacuum technology, can be adapted to large structures and can improve the corrosion-resisting quality of existing oxide films on metal or alloy surfaces.
