Corrosion engineering

Stress concentration factor

Materials science; Corrosion engineering

A multiplying factor for applied stress that allows for the presence of a structural discontinuity such as a notch or hole; K t equals the ratio of the greatest stress in the region of the ...

Transition temperature

Materials science; Corrosion engineering

(1) An arbitrarily defined temperature that lies within the temperature range in which metal fracture characteristics (as usually determined by tests of notched specimens) change rapidly, such as ...

A metastable aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures below the pearlite range but above the martensite start temperature. Bainite formed in ...

Polarisation curve

Materials science; Corrosion engineering

A plot of r current density versus electrode potential for a specific electrode-electrolyte combination.

Oxidation

Materials science; Corrosion engineering

(1) A reaction in which there is an increase in valence resulting from a loss of electrons. Contrast with reduction. (2) A corrosion reaction in which the corroded metal forms an oxide; usually ...

Cation

Materials science; Corrosion engineering

A positively charged ion that migrates through the electrolyte toward the cathode under the influence of a potential gradient. See also anion and ion.

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 ...
