Corrosion engineering
Transpassive state
Materials science; Corrosion engineering
(1) State of anodically passivated metal characterised by a considerable increase of the corrosion current, in the; absence of pitting, when the potential is increased. (2) The noble region of ...
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 ...
Sour gas
Materials science; Corrosion engineering
A gaseous environment containing hydrogen sulphide and carbon dioxide in hydrocarbon reservoirs. Prolonged exposure to sour gas can lead to hydrogen damage, sulfide-stress cracking, and/or ...
Green rot
Materials science; Corrosion engineering
A form of high-temperature corrosion of chromium-bearing alloys in which green chromium oxide (Cr 2 O 3 ) forms, but certain other alloy constituents remain metallic; some simultaneous carburization ...
Wash primer
Materials science; Corrosion engineering
A thin, inhibiting paint, usually chromate pigmented with a polyvinyl butyrate binder.
Additive
Materials science; Corrosion engineering
A substance added in a small amount, usually to a fluid, for a special purpose, such as to reduce friction, corrosion, etc.
Electropolishing
Materials science; Corrosion engineering
A technique commonly used to prepare metallographic specimens, in which a high polish is produced by making the specimen the anode in an electrolytic cell, where preferential dissolution at high ...
