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.

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

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>

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 ...

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.

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.
