Corrosion engineering

sour gas

Materials science; Corrosion engineering

A gaseous environment containing hydrogen sulfide and carbon dioxide in hydrocarbon reservoirs. Prolonged exposure to sour gas can lead to hydrogen damage, sulfide-stress cracking, and/or ...

A type of wear that occurs between tight-fitting surfaces subjected to cyclic relative motion of extremely small amplitude. Usually, fretting is accompanied by corrosion, especially of the very fine ...

failure

Materials science; Corrosion engineering

A general term used to imply that a part in service (1) has become completely inoperable, (2) is still operable but is incapable of satisfactorily performing its intended function, or (3) has ...

chelating agent

Materials science; Corrosion engineering

(1) An organic compound in which atoms form more than one coordinate bond with metals in solution. (2) A substance used in metal finishing to control or eliminate certain metallic ions present in ...

reducing agent

Materials science; Corrosion engineering

A compound that causes reduction, thereby itself becoming oxidized.

transpassive state

Materials science; Corrosion engineering

(1) State of anodically passivated metal characterized by a considerable increase of the corrosion current, in the; absence of pitting, when the potential is increased. (2) The noble region of ...
