(1) The removal of oxygen from molten metals by use of suitable deoxidixers. (2) Sometimes refers to the removal of undesirable elements other than oxygen by the introduction of elements or compounds that readily react with them. (3) In metal finishing, t ...

Pertaining to the body-centered cubic crystal structure (BCC) of many ferrous (iron-base) metals.

A powerfully oxidizing allotropic form of the element oxygen. The ozone molecule contains three atoms (O3). Ozone gas is decidedly blue, and both liquid and solid ozone are an opaque blue-black color, similar to that of ink.

Electrode reaction equivalent to a transfer of negative charge from the electronic to the ionic conductor. A cathodic reaction is a reduction process. An example common in corrosion is: Ox + ne s Red.

Electrolytic pickling in which the work is the cathode.

A pattern of parallel surface cracks that are formed by alternate rapid heating and cooling of the extreme surface metal, sometimes found on forging dies and piercing punches. There may be two sets of parallel cracks one set perpendicular to the other.

A black finish on a metal produced by immersing it in hot oxidizing salts or salt solutions.

The electroplating of zinc upon iron or steels

A type of inhibitor that appreciably changes the potential of u metal to a more noble (positive) value.

Embrittlement of stainless steels upon extended exposure to temperatures between 400 and 510

Cracking that occurs in the weld metal. See also cold cracking, hot cracking, lamellar tearing, and stress-relief cracking.

The electrolyte adjacent to the cathode of an electrolytic cell.

The algebraic ratio of two specified stress values in a stress cycle. Two commonly used stress ratios are: (1) the ratio of the alternating stress amplitude to the mean stress. A = Sa/Sm and (2) the ratio of the minimum stress to the maximum stress. R =Sm ...

A term primarily used in Europe to describe galvanic corrosion between dissimilar metals.

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.

(1) A cell, the emf of which is due to the potential difference between a metal in an active state and the same metal in a passive state. (2) A corrosion cell in which the anode is a metal in the active state and the cathode is the same metal in the passi ...

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

The portion of solution in immediate contact with the cathode during electrolysis.

The degradation of a solid body resulting from its exposure to cavitation. This may include loss of material, surface deformation, or changes in properties or appearance.

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