Corrosion engineering

Anodic inhibitor

Materials science; Corrosion engineering

A chemical substance or combination of substances that prevent or reduce the rate of the anodic or oxidation reaction by a physical, physico-chemical or chemical action.

Tensile stress

Materials science; Corrosion engineering

A stress that causes two parts of an elastic body. on either side of a typical stress plane, to pull apart. Contrast with compressive stress.

Hydrogen damage

Materials science; Corrosion engineering

A general term for the embrittlement, cracking, blistering. and hydride formation that can occur when hydrogen is present in some metals.

A pattern of parallel surface cracks that are formed by alternate rapid heating and cooling of the extreme surface metal, sometimes found on forging dies and piercing punches. There may be two sets ...

Ground bed

Materials science; Corrosion engineering

A buried item, such as junk steel or graphite rods, that serves as the anode for the cathodic protection of pipelines or other buried structures. See also deep ground bed.

Diffusion coefficient

Materials science; Corrosion engineering

A factor of proportionality representing the amount of substance diffusing across a unit area through a unit concentration gradient in unit time.

Cold cracking

Materials science; Corrosion engineering

A type of weld cracking that usually occurs below 203C (400F). Cracking may occur during or after cooling to room temperature, sometimes with a considerable time delay. Three factors combine to ...
