Chapter 8: Anti-corrosive Applications of Iron, Copper and Titanium Oxides

When metals come into contact with moisture and air, they liberate electrons and form metallic ions. Corrosion is a natural, spontaneous process that results in the metal being stable. Corrosion may be controlled in several ways. For many engineering fields, nanotechnology is an emerging solution for protecting metals and alloys against various extreme corrosive conditions. Metal oxide nanoparticles (MNPs) have been used to prevent corrosion in different structural materials, including steels, copper, aluminum, and magnesium alloys. MNPs have been generated using a variety of processes, including sol–gel, anodization, electroplating, and electroless plating. This chapter focuses on the fundamental science, synthesis, characterization, and anti-corrosive application of copper oxide, titanium oxide, and iron oxide.
