In the last two decades, nanotechnology has been playing an increasing important role in supporting innovative technological advances to manage the corrosion steel. This paper reviews various recent patents and patent applications related to the management of steel corrosion, including the use of nanotechnology to produce high-performance steel, to produce coatings with superior abrasion resistance and good corrosion resistance, to enhance the surface of steel designed for oxidizing and corrosive environments, and to prepare nano-sized additives for anti-corrosion coatings or intelligent corrosion protection systems, or for reducing the corrosion risk of the service environment. The 16 inventions reviewed concern a period extending from the years 2005 up to date. The paper concludes with a discussion of current and future developments expected in the subjects covered.
