Abstract

Advanced coating systems have been developed to address the challenges of coating life and corrosion mechanisms in various industries. These coating systems are designed to provide enhanced protection, prolong the lifespan of coated surfaces, and reduce the effects of corrosion. A corrosion study with respect to contaminants (water soluble salts like sulphates, chlorides and nitrates etc.), design of the components (macro and micro defects developed due to improper design and physic-chemical behaviour of coatings (adhesion, permeation of air and moisture) etc. was done by several scientist and found that these elements prove to be the deciding factors in rate of corrosion. In addition to metal surface preparation, coating thickness, permeability to water and oxygen, and coating chemistry, the existence of soluble salts (chloride, nitrate, and sulphate) and their effect on the coating-metal interface were investigated. Corrosion is also a result of macroscopic flaws brought on by poor handling, design, and construction. Surface irregularities have their own role in determining the life of the coating. The corrosion process can be slowed down or stopped by certain coating solutions.

Keywords: Corrosion, contaminants, resins, coatings, corrosion mechanism.
