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

Pertaining to forces on a body or part of a body that tend to crush or compress the body.

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

A list of metals and alloys arranged according to their relative corrosion potentials in a given environment. Compare with electromotive series.

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

(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.

A thin, not necessarily visible, layer of material.

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.

This potential, sometimes called zeta potential, is a potential difference in the solution caused by residual, unbalanced charge distribution in the adjoining solution, producing a double layer. The electrokinetic potential is different from the electrode ...

(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 ...

The test or specimen electrode in an electrochemical cell.

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.

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 ( ...

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

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 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.

An assembly, consisting of a vessel, electrodes, and an electrolyte, in which electrolysis can be carried out.

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

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.

System consisting of one or more metals and all parts of the environment that influence corrosion.
