A compound that causes oxidation, thereby itself being reduced.

An aqueous solution containing one gram equivalent of the active reagent in 1L of the solution.

A composite metal containing, two or more layers that have been bonded together. The bonding may have been accomplished by co-rolling, co-extrusion, welding, diffusion bonding, casting, heavy chemical deposition, heavy electroplating, or explosive claddin ...

The process in which a metal fractures prematurely under conditions of simultaneous corrosion and repeated cyclic loading at lower stress levels or fewer cycles than would be required in the absence of the corrosive environment.

The selective attack of one or more components of a solid solution alloy; eg. dezincification, dealumination etc. See dealloying.

An atmosphere in an area of heavy industry with soot, fly ash, and sulfur compounds as the principal constituents.

The electrolyte adjacent to the cathode of an electrolytic cell.

A process involving conjoint corrosion and cavitation.

The ratio of the electric current density to the electric field in a material. Also called electrical conductivity or specific conductance.

A form of deterioration that is distributed more or less uniformly over a surface; See uniform corrosion.

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

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 ...

That portion of the base metal that was not melted during brazing, cutting, or welding, but whose microstructure and mechanical properties were altered by the heat; Refers to area adjacent to a weld where the thermal cycle has coused microstructural chang ...

An accelerated corrosion test for some electrodeposits for anodic coatings on aluminum.

Deposition of a metal or compound on a heated surface by reduction or decomposition of a volatile compound at a temperature below the melting points of the deposit and the base material. The reduction is usually accomplished by a gaseous reducing agent su ...

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

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

Localized corrosion of a metal surface at, or immediately adjacent to, an area that is shielded from full exposure to the environment because of close proximity between the metal and the surface of another material.

Electroplating tin on an object.

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