Electrolytic pickling in which the work is the cathode.

A process in which metal ions in a dilute aqueous solution are plated out on a substrate by means of autocatalytic chemical reduction.

(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 stress that will cause fracture in a creep test at a given time in a specified constant environment. Also called stress-rupture strength.

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

The part of the total carbon in steel or cast iron that is present as other than free carbon.

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

Electrode reaction equivalent to a transfer of negative charge from the electronic to the ionic conductor. A cathodic reaction is a reduction process. An example common in corrosion is: Ox + ne s Red.

The destruction of adhesion between a coating and the surface coated.

The electroplating of zinc upon iron or steels

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

The electrolyte adjacent to the cathode of an electrolytic cell.

(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 applied to reaction with a gas containing elemental oxygen, s ...

The potential of a corroding surface in an electrolyte, relative to a reference electrode. Also called rest potential, open circuit potential, or freely corroding potential.

An instrument for indicating or measuring a small electric current by means of a mechanical motion derived from electromagnetic or electrodynamic forces produced by the current.

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.

A network of checks or cracks appearing on the surface.

Fracture of a metal during quenching from elevated temperature. Most frequently observed in hardened carbon steel, alloy steel, or tool steel parts of high hardness and low toughness. Cracks often emanate from fillets, holes, corners, or other stress rais ...

A substance that produces depolarization.

The range of the stress-intensity factor during a fatigue cycle.
