That portion of the polarization of a cell produced by concentration changes resulting from passage of' current through the electrolyte.

System consisting of one or more metals and all parts of the environment that influence corrosion.

Interfacial reaction equivalent to a transfer of charge between electronic and ionic conductors. See also anodic reaction and cathodic reaction.

Water that contains certain salts, such as those of calcium or magnesium, which form insoluble deposits in boilers and form precipitates with soap.

This potential, sometimes called zeta potential, is a potential difference in the solution caused by residual, unbalanced charge distribution in the adjoining solution, producing a double layer. The electrokinetic potential is different from the electrode ...

An electrolytic cell, the electromotive force of which is caused by a difference in concentration of some component in the electrolyte. This difference leads to the formation of discrete cathode and anode regions.

Accelerated corrosion of a metal because of an electrical contact with a more noble metal or nonmetallic conductor in a corrosive electrolyte.

To coat a metal surface with zinc using any of various processes.

An experimental technique where by an electrode is maintained at a constant current in an electrolyte.

A list of metals and alloys arranged according to their relative corrosion potentials in a given environment. Compare with electromotive series.

Depositing filler metal on a surfsae by welding, spraying, or braze welding to increase resistance to abrasion, erosion, wear, galling. impact, or cavitation damage.

Being or composed of hydrocarbons or their derivatives, or matter of plant or animal origin. Contrast with inorganic.

The severe loss of ductility of a metal resulting from corrosive attack, usually inter,granular and often not visually apparent.

In a thermodynamic system of several constituents, the rate of change of the Gibbs function of the system with respect to the change in the number of moles of a particular constituent.

See auxiliary electrode.

A reaction in which there is a decrease in valence resulting from a gain in electrons. Contrast with oxidation.

Tendency of an environment to cause corrosion in a given corrosion system.

The electric current that flows between metals or conductive nonmetal in a galvanic couple.
