CORROSION COATINGS

Abstract

Corrosion is a significant challenge in industries involving metals, causing degradation that leads to failure of components, increased maintenance costs, and safety hazards. Corrosion coatings serve as a crucial protective barrier, preventing or minimizing the interaction between metal surfaces and corrosive environments. This paper comprehensively reviews various types of corrosion coatings, their materials, application methods, mechanisms of protection, and effectiveness in different environments. The research focuses on organic coatings such as paints and polymers, inorganic coatings including metallic and ceramic layers, and novel smart coatings that respond to environmental stimuli. Comparative analyses are presented on the performance, durability, and economic viability of these coatings. Application techniques such as spraying, electroplating, and chemical vapor deposition are discussed in detail, with emphasis on how coating thickness, adhesion, and uniformity influence corrosion resistance
