Electroplating tin on an object.

The test or specimen electrode in an electrochemical cell.

The potential of a reversible oxidation-reduction electrode measured with respect to a reference electrode, corrected to the hydrogen electrode, in a given electrolyte.

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>

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

Chromium plated for engineering rather than decorative applicactions.

Plating wherein fine metal powders are peened onto the work by tumbling or other means.

Deterioration of metals as a result of the metabolic activity of microorganisms.

See principal stress (normal).

Rapid cooling of metals (often steels) from a suitable elevated temperature. This generally is accomplished by immersion in water, oil, polymer solution, or salt, although forced air is sometimes used.

A type of weld cracking that usually occurs below 203

The maximum cyclic stress value that a metal can with stand for a specified number of cycles or length of time in a given corrosive environment. See corrosion fatigue strength

The positive direction of electrode potential, thus resembling noble metals such as gold and platinum.

Embrittlement resulting from bombardment with neutrons, usually encountered in metals that have been exposed to a neutron flux in the core of a reactor. In steels, neutron embrittlement is evidenced by a rise in the ductile-to-brittle transition temperatu ...

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.

(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 ...

A coating process, similar to gas carburizing and carbonitriding, whereby a reactant atmosphere gas is fed into a processing chamber where it decomposes at the surface of the workpiece, liberating one material for either absorption by, or accumulation on ...

Corrosion which is increased because of the abrasive action of a moving stream; the presence of suspended particles greatly accelerates abrasive action.See erosion-corrosion.

An equation that expresses the exact electromotive force of a cell in terms of the activities of products and reactants of the cell.

A glass membrane electrode used to measure pH or hydrogen-ion activity.
