Corrosion engineering
chelation
Materials science; Corrosion engineering
A chemical process involving formation of a heterocyclic ring compound that contains at least one metal cation or hydrogen ion in the ring.
uniform corrosion
Materials science; Corrosion engineering
(1) A type of corrosion attack (deterioration) uniformly distributed over metal surface. (2) Corrosion that proceeds at approximately the same rate over a metal surface. Also called general ...
acid embrittlement
Materials science; Corrosion engineering
A form of hydrogen embrittlement that may be induced in some metals by acid.
organic acid
Materials science; Corrosion engineering
A chemical compound with one or more carboxyl radicals (COOH) in its structure; examples are butyric acid, CH 3 (CH 2 ) 2 COOH; maleic acid, HOOCCH-CHCOOH; and benzoic acid, C 6 H 5 COOH.
voids
Materials science; Corrosion engineering
A term generally applied to paints to describe holidays, holes, and skips in a film. Also used to describe shrinkage in castings and weld.
dummy cathode
Materials science; Corrosion engineering
(1) A cathode, usually corrugated to give variable current densities, that is plated at low current densities to preferentially remove impurities from a plating solution. (2) A substitute cathode ...
hematite
Materials science; Corrosion engineering
(1) An iron mineral crystallizing in therhombohedral system; the most important are of iron. (2) An iron oxide, Fe,O,, corresponding to an iron content of approximately 70%.
