Chapter 24 - Corrosion inhibition of materials at nanoscale

Abstract

Corrosion is an unavoidable process with technological and economic significance. Therefore it receives much attention in the research community to find ways to decrease the economic losses due to corrosion. A corrosion inhibitor is a chemical compound applied to a specific environment (liquid or gas) to decrease the corrosion rate of the material. Nanocoatings would improve corrosion protection because these coatings have properties like surface hardness, smoother thickness, adhesive quality, and high-temperature corrosion opposition. There is a degradation of solar cells due to the intrinsic ionic defects and corrosion of common electrodes. Materials such as ZnO/Al2O3 core-shell nanorod array, benzotriazole, graphene interlayer, and nitrogen-containing heterocyclics can be used to reduce metallic corrosion and to enhance the performance of the solar cells. The main purpose of this chapter is to provide a comprehensive study of metal corrosion and its management.
