Corrosion engineering

localized corrosion

Materials science; Corrosion engineering

Corrosion at discrete sites, stress-corrosion cracking.

local action

Materials science; Corrosion engineering

Corrosion due to the action of "local cells," that is, galvanic cells resulting from inhomogeneities between adjacent areas on a metal surface exposed to an electrolyte.

corrosion rate

Materials science; Corrosion engineering

Corrosion effect on a metal per unit of time. The type of corrosion rate used depends on the technical system and on the type of corrosion effect. Thus, corrosion rate may be expressed as an ...

decobaltification

Materials science; Corrosion engineering

Corrosion in which cobalt is selectively leached from cobalt-base alloys, such as Stellite, or from cemented carbides. See also dealloying and selective leaching.

denickelification

Materials science; Corrosion engineering

Corrosion in which nickel is selectively leached from nickel-containing alloys. Most commonly observed in copper-nickel alloys after extended service in fresh water. See also dealloying, and ...

Corrosion in which one element is preferentially removed from an alloy, leaving a residue (often porous) of the elements that are more resistant to the particular environment. Also called dealloying ...

dezincification

Materials science; Corrosion engineering

Corrosion in which zinc is selectively leached from zinc-containing alloys. Most commonly found in copper-zinc alloys containing less than 83% copper after extended service in water containing ...
