Nanoparticles are being considered in the development of durable coating systems due to their beneficial electrical and mechanical properties. The present study aims to investigate the corrosion performance of a nanoparticle enriched zinc rich primer (NPE-ZRP) for structural steel in aggressive marine exposure.
An optical fiber corrosion sensor is developed to monitor the penetration of corrosion pits in steel bars. Simply made by encasing one end of an optical fiber into a steel straw. As corrosion penetrates the steel straw wall, the solution and corrosion products fill inside and contaminate the fiber end surface, resulting in a change in the reflectivity.
