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

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

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

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.

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.

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>

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

See principal stress (normal).

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.

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 ...

Electroplating tin on an object.

A type of weld cracking that usually occurs below 203

The chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.

Introducing nitrogen into the surface layer of a solid ferrous alloy by holding at a suitable temperature (below Ac1 for ferritic steels) in contact with a nitrogenous material, usually ammonia or molten cyanide of appropriate composition. Quenching is no ...

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

Chromium plated for engineering rather than decorative applicactions.

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

A fracture, usually of' polycrystalline metal, in which most of the grains have failed by cleavage, resulting in bright reflecting facets. It is associated with low-energy brittle fracture.
