Passivation is the process by which steel rebars resist corrosion. When exposed to air and moisture, a thin layer of iron oxide is formed on the surface of the steel. This layer, commonly known as rust, acts as a protective barrier, preventing oxygen and moisture from reaching the inner layers of steel and halting further oxidation. To provide an additional layer of protection against corrosion, steel rebars are often coated with materials like epoxy or zinc. These coatings create a physical barrier, shielding the steel from the corrosive elements of the environment. Regular maintenance, which includes cleaning and applying protective coatings, can also contribute to prolonging the lifespan of steel rebars and preventing corrosion.
Steel rebars resist corrosion through a process called passivation. When the steel is exposed to air and moisture, a thin layer of iron oxide forms on its surface, which acts as a protective barrier against further corrosion. This layer, also known as rust, prevents oxygen and moisture from reaching the inner layers of steel, thereby preventing further oxidation. Additionally, steel rebars are often coated with materials such as epoxy or zinc to provide an extra layer of protection against corrosion. These coatings act as a physical barrier between the steel and the environment, preventing contact with corrosive elements. Regular maintenance, such as cleaning and applying protective coatings, can also help to extend the lifespan of steel rebars and prevent corrosion.
Steel rebars resist corrosion due to the presence of a protective oxide layer that forms on their surface when exposed to oxygen and moisture. This oxide layer acts as a barrier, preventing further contact between the steel and corrosive agents, thus extending the rebars' lifespan and durability.
