Aging induced by rapid cooling after solution heat treatment.

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

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

An accelerated corrosion test in which specimens are exposed to a fine mist of a solution usually containing sodium chloride, but sometimes modified with other chemicals.

A thin, tightly adhering oxide skin (only a few molecules thick) that forms when steel is tempered at a low temperature, or for a short time, in air or a mildly oxidizing atmosphere. The color, which ranges from straw to blue depending on the thickness of ...

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

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

(Galvanic Corrosion) Corrosion resulting from dissimilar metal contact.

A decrease in the polarization of an electrode; the elimination or reduction of polarization by physical or chemical means; depolarization results in increased corrosion.

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

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

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

In austenitic stainless steels the precipitation of chromium carbides, usually at grain boundaries, on exposure to temperatures of about 550 to 850

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.

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

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

The rate of crack extension caused by constant-amplitude fatigue loading, expressed in terms of crack extension per cycle of load application.

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

An imprecise term used to denote a treatment given cold-worked material to reduce its strength to a controlled level or to effect stress relief. To be meaningful, the type of material, the degree of cold work, and the time-temperature schedule must be sta ...

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