A visible corrosion product consisting of hydrated oxides of iron. Applied only to ferrous alloys. See also white rust.

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

Splitting (fracture) of a crystal on a crystallographic plane of' low index.

A cell developed in an electrolyte resulting from electrical contact between two dissimilar metals. See galvanic corrosion.

A metastable lamellar aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures above the bainite range.

Foreign substance which comes from the environment, adhering to a surface of a material

Ability of a metal to withstand corrosion in a given corrosion system.

The ratio of the electrochemical equivalent current density for a specific reaction to the total applied current density.

(1) The amount of any substance dissolved or deposited in electrolysis is proportional to the total electric charge passed. (2) The amounts of different substances dissolved or deposited by the passage of the same electric charge are proportional to their ...

The development of slight breaks in a coating that do not penetrate to the underlying surface.

The mass of unit volume of a material at a specified temperature.

A compound with a central atom or ion bound to a group of ions or molecules surrounding it. Also called coordination complex. See also chelate, complexation, and ligand.

(Galvanic Corrosion) Corrosion resulting from dissimilar metal contact.

The liquid material remaining from pulpwood cooking in the soda or sulfate paper-making process.

A pair of dissimilar conductors, commonly metals, in electrical contact. See also galvanic corrosion.

An anode that is insoluble in the electrolyte under the conditions prevailing in the electrolysis.

The number of cycles of stress that can be sustained prior to failure under a stated test condition.

A movement of electrons in an external circuit connecting an anode and cathode in a corrosion cell; the current flow is arbitrarily considered to be in an opposite direction to the electron flow.
