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

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

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 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 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 ...

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

(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 ...

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.

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

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

One of the group of l5 chemically similar metals with atomic numbers 57 through 7l, commonly referred to as the lanthanides.

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.

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

Depositing a metallic coating on a metal immersed in a liquid solution, without the aid of an external electric current. Also called dip plating.

See exfoliation corrosion.
