Acid Immersion Strong Chlorides Galvanic Reactions Transplanted Plain Iron or Steel Lack of Oxygen Temperature Extremes WebA substance that causes corrosion is called a corrosive substance, or simply, a corrosive. A corrosive can damage living tissue as well as inanimate materials. The rusting of iron is a well-known example of corrosion. Other metals may be similarly damaged, typically producing their oxides, hydroxides, and salts. WebOn some metals, corrosion actually serves as a type of protection. Aluminum oxide, copper carbonate and chromium oxide, for instance, act as protective coatings for the underlying metals. Rust that forms on iron, however, cannot protect the iron from further corrosion because it's too porous. procedury covid-19
