Construction of columns and bridges for sea transportation, where corrosion resistance is a major factor, is the most common use of weathering steel, it is a low carbon alloy steel. Under the correct environmental circumstances, weathering steel develops an adherent protective coating on its surface. Patina is the protective layer that develops on the surface of weathering steel. It protects against further corrosion occurring to the structure. Since these weathering steels are repeatedly exposed to a wet environment, their corrosion resistance decreases. Our research focuses on investigations of the coatings used on weathering steel to increase its corrosion resistance in marine conditions. The coatings applied on the substrate were poly urea, polyurethane, epoxy and black enamel. Immersion test, salt spray test and potentio-dynamic test were performed on the coated samples to determine how they would react to various conditions. The depth of the corrosion on the coatings was confirmed by the profilometry test. Based on corrosion tests, the conclusion that polyurea is the best coating, followed by polyurethane, black enamel, and epoxy, based on the corrosion studies.

“…The simple precise belongings of weathering steels are their stepped forward corrosion resistance in atmospheric conditions. Polymeric coatings are coatings or paint made with polymers that offer advanced adherence and safety from corrosion [21][22][23][24][25]. The polymeric coating system applies an elastomer or different polymeric cloth onto a helping substrate.…”

“…Polymeric coatings are required to stick nicely to the substrate and should now no longer chip effortlessly or degrade from heat/moisture/salt, or chemicals.

Weathering steel, a low carbon alloy steel, most widely used in marine transportation and construction fields like bridges, sculptures where corrosion resistance is the main concern. Weathering steel creates an adhering protective coating on its surface in the right environmental conditions. The protective layer which is formed on the surface weathering steel known as patina. It protects the structure from further corrosion to occur. When these weathering steels are continuously exposed to moisture environment its corrosion resistance decreases. So, our investigation deals about the studies of the coatings used on weathering steel to increase its corrosion resistance in marine conditions. The coatings applied on the substrate were poly urea, polyurethane, epoxy and black enamel. Corrosion tests were performed on these coated samples to evaluate their corrosion behaviour in different environments. Corrosion tests that were performed are immersion test, salt spray test and potentio-dynamic test. The profilometry test is investigated and it confirmed the depth of the corrosion on the coatings. Based on the corrosion studies, we conclude that poly urea is the excellent coating followed by polyurethane, black enamel and epoxy.
