Corrosion is the gradual degradation of materials, typically metals, due to chemical reactions with their environment, often leading to loss of material strength.

The most common form of corrosion in steel structures is rusting, which occurs when iron reacts with oxygen and water.

Galvanic corrosion occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, causing one metal to corrode faster than the other.

Pitting corrosion is localized corrosion that creates small holes or pits in the metal surface, often leading to structural weakness.

Corrosion can be prevented by coating the material with protective layers, using corrosion-resistant materials, and reducing exposure to moisture and chemicals.

Stress corrosion cracking is the growth of cracks in a material caused by the combined effects of tensile stress and a corrosive environment.

Cathodic protection works by making the protected material the cathode of an electrochemical cell, thus preventing corrosion from occurring.

Corrosion reduces the material’s strength, making it more susceptible to failures and affecting its durability and functionality.

Galvanic corrosion occurs when two dissimilar metals are electrically connected and exposed to an electrolyte, leading to corrosion of the less noble metal.
