How Corrosion Damages Power Plants - Polygon Group

Salts, high temperatures and acids can accelerate oxidation. Hot, or dry, corrosion is a type of oxidation that occurs in the absence of moisture, when a surface has a thin film of salt in an oxidizing gas coating it. This type of corrosion affects gas turbines, incinerators, boilers and internal combustion engines.
