Among the metals affected by this type of corrosion are stainless steel, certain magnesium alloys, and the copper-bearing aluminum alloys. Intergranular corrosion occurs in certain grades of stainless steel when the steel is heated, as in welding. Brittleness results, causing the metal to crack near the weld. For this reason, a post-weld heat treatment is needed before reinstalling stainless steel parts that have been welded.
Corrosion Prevention of reinforced concrete structures is an increasingly important method of repairing and protecting spalling concrete, damaged bridges, steel framed buildings, harbours, wharves and other structures.orrosion is probably the single most serious cause of deterioration of reinforced concrete structures. Buildings and bridges are suffering from corrosion because of contamination by de-icing salt, sea salt and salts cast into the concrete and the carbonation of concrete.
