Abstract
Carbon nanotubes are attractive and promising fillers due to their chemical inertness and high mechanical, electrical, and thermal properties. From the conjugation of carbon nanotubes with inorganic hybrid, it is expected to obtain nanocomposite coatings that combine high anti-corrosion efficiency with improved mechanical stability. This book chapter presents a concise review of microstructure and corrosion behaviour of different nanotube composite coatings. In the first section, the authors briefly explain the science behind the corrosion and corrosion resistance of nanotube composite coatings, followed by a selection of current state and recent advances on promoted nanotube composite coating: Al, Cu, Mg, Fe, Ni, Mg–Zn, Mg–Al, NiCo, and ZnCo-carbon nanotube composite and based matrix composites coatings. Recent development of graphene reinforced metal matrix nanocomposites has been studied. Challenges needed to be rectified before the synthesis of metal-matrix nanocomposites. Finally, the authors discuss the relevant topics, highlighting recent progress and unresolved questions.
