Analysis of the use of efficient coatings for metallic structures in corrosive environments

Abstract

This research examines the use of efficient coatings on metal structures in corrosive environments, aiming to optimize their protection and extend their service life. A mixed approach is employed, combining quantitative analyses (laboratory tests) and qualitative assessments (evaluation of properties and challenges). The methodology includes a comprehensive review of academic literature, such as theses, scientific articles, and international standards, to identify trends and best practices in anti-corrosion protection. The main findings highlight that coatings based on epoxy resins, polyurethanes, and multilayer systems (with zinc-rich layers, intermediate epoxy layers, and polyurethane finishes) offer superior performance. These systems exhibit high corrosion resistance, durability in harsh conditions, and excellent adhesion to metal surfaces, even in environments with moisture and chemicals. It is concluded that the choice of coating should align with operational conditions and substrate properties, emphasizing the importance of a comprehensive approach in their selection and application. This study provides a solid foundation for future research and industrial applications.
