Corrosion and Corrosion Protection of Unio in Carbonic Acid Medium
Abstract: Unio is a calciferous animal, and its outer surface is made of calcium carbonate. It usually happens in sources of sweet water. They create carbonic acid by absorbing carbon dioxide. It changes the pH of sweet water sources thus water becomes acidic. It develops corrosive environment for Unio. Carbonic acid interacts with Unio to form corrosion cells on the interface of Unio. This acid oxidizes calcium carbonate into calcium ions …

Polymeric Coating Applied for Corrosion Protection of Mild Steel in Corrosive Medium
Abstract: Mild steel is coated with a polymer layer of polybutadiene for protection. However, this coating does not effectively safeguard the metal in environments containing moisture, sulphur dioxide, or chloride. These pollutants interact with the polybutadiene-coated surface, creating a highly corrosive atmosphere. Moisture condenses on the coated metal surface and absorbs sulphur dioxide, forming sulphuric acid. This acid initiates both chemical and electrochemical reactions with the polymer-coated metal, accelerating the corrosion …
