Why Does Metals Rust? Sea water is one of the most complex and aggressive media. The corrosion caused due to seawater depends on numerous interdependent parameters and combines chemical, biological and mechanical factors. Understanding the influence of each of these parameters and factors is key to optimizing the design of metal structures and equipment used in marine environments. This is also the key to optimizing corrosion protection methods and material performance. Localized corrosion is a particularly insidious deterioration phenomenon and therefore a threat to the integrity of the metal structure. Solid rust products built into the surface of the metal are the main effects of metal degradation. They can greatly affect the process of continuous corrosion. The mettalic surface gets porous and thus provide a unique habitat for microbes that can develop in a particular area. Also, some categories are electronic conductors, for example, magnetite and iron sulfide, which can harvest galvanic cells. The composition of the rust product layer also varies with the area of exposure and can change over time. Get Free Consutation Today. BENZ Packaging Solutions Pvt Ltd +91 9899144488
