Abstract
Corrosion significantly affects the performance and durability of any material and as such is an important determining factor in critical industries like marine, aerospace, aircraft and construction. The corrosion behaviour of any material is determined not only by the material itself but also by the interaction of the material with the environment and many other allied factors. A clear understanding of corrosion process is thus of utmost importance for the proper selection of the materials in any given environment and for their effective use for engineering and industrial applications. In this paper, a comprehensive review of different studies carried out to analyse the corrosion behaviour of different metals and other materials in different environments is presented. Also, details about various inhibitors and reinforcements having varying effects on the corrosion behaviour of different materials are presented. A section is dedicated to discuss the various corrosion evaluation methods suitable for a particular environment. Further, special focus has been laid to discuss the various methods to evaluate corrosion and various corrosive environments to which the materials are susceptible. The literature revealed that the material–environment interactions and other various factors greatly affect the corrosion behaviour of the materials. The paper apart from presenting fundamentals related to corrosion testing shall also present the literature related to the corrosion behaviour of various critical engineering materials, and the paper shall act as a stimulant for future research.
