(1) An organic compound in which atoms form more than one coordinate bond with metals in solution. (2) A substance used in metal finishing to control or eliminate certain metallic ions present in undesirable quantities.

Aging induced by rapid cooling after solution heat treatment.

Progressive loss of original material from a solid surface due to continuing exposure to cavitation.

The relative ability of a ferrous alloy to form martensite when quenched from a temperature above the upper critical temperature. Hardenability is commonly measured as the distance below a quenched surfsce at which the metal exhibits a specific hardness ( ...

The process of prior removal of the active corrosive constituents usually oxygen, from a corrosive liquid by controlled corrosion of expendable metal or by other chemical means, thereby making the liquid less corrosive.

A chemical process involving formation of a heterocyclic ring compound that contains at least one metal cation or hydrogen ion in the ring.

A movement of electrons in an external circuit connecting an anode and cathode in a corrosion cell; the current flow is arbitrarily considered to be in an opposite direction to the electron flow.

A compound that causes oxidation, thereby itself being reduced.

A thin, not necessarily visible, layer of material.

Corrosion in which cobalt is selectively leached from cobalt-base alloys, such as Stellite

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

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

Corrosion that occurs under some coatings in the form of randomly distributed threadlike filaments.

Any of the elements of the halogen family, consisting of fluorine, chlorine, bromine, iodine, and astatine.

The potential of an electrode measured with respect to a reference electrode or another electrode when no current flows to or from it.

The ability of a solution to give satisfactory plating at very low current densities. a condition that exists in recesses and pits. This term suggests an ability to cover, but not necessarily to build up, a uniform coating, whereas throwing power suggests ...

The development of loose removable powder at the surface of an organic coating usually caused by weathering.

Performing a chromate treatment

Electroplating tin on an object.
