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

The binding of an adsorbate to the surface of a solid by forces whose energy levels approximate those of a chemical bond. Contrast with physisorption.

Localized corrosion frequently observed in oilwell tubing in which a circumfrential attack is observed near a region of metal "upset".

The molecule, ion, or group bound to the central atom in a chelate or a coordination compound.

The test or specimen electrode in an electrochemical cell.

Pertaining to forces on a body or part of a body that tend to crush or compress the body.

Aging under conditions of time and temperature greater than those required to obtain maximum change in a certain property, so that the property is altered in the direction of the initial value.,/dd>

An index calculated from total dissolved solids, calcium concentration, total alkalinity, pH and solution temperature that shows the tendency of a water solution to precipitate or dissolve calcium carbonate.

A thin, not necessarily visible, layer of material.

Heating a ferrous alloy to a suitable temperature above the transformation range and then cooling in air to a temperature substantially below the transformation range.

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

A compound that causes oxidation, thereby itself being reduced.

See exfoliation corrosion.

Depositing a metallic coating on a metal immersed in a liquid solution, without the aid of an external electric current. Also called dip plating.

The maximum repeated stress that can he endured by a metal without failure under definite conditions of corrosion and fatigue and for a specific number of stress cycles and a specified period of time.

A state of resistance to corrosion or anodic dissolution of a metal caused by thermodynamic stability of the metal.

See principal stress (normal).

A type of weld cracking that usually occurs below 203

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 ...

(1) A metal whose potential is highly positive relative to the hydrogen electrode. (2) A metal with marked resistance to chemical reaction, particularly to oxidation and to evolution by inorganic acids. The term as often used is synonymous with precious m ...
