Pitting resulting from ablation, outgassing or meteor contact.

Deterioration of material caused by ion impact.

Brittle fracture of a metal in which the fracture is between the grains, or crystals, that form the metal. Also called intercrystalline fracture. Contrast with transgranular fracture.

Coating metal with a very thin layer of molten solder or brazing filler metal.

See hydrogen embrittlement.

Being or composed of matter other than hydrocarbons and their derivatives, or matter that is not of plant or animal origin. Contrast with organic.

A single, solid, homogeneous crystalline phase containing two or more chemical species.

An instrument for automatically maintaining an electrode in an electrolyte at a constant potential or controlled potentials with respect to a suitable reference electrode.

See hydrogen embrittlement.

Any metallic structure that is not intended as part of a cathodic protection system of interest.

Corrosion potential in the absence of net electrical current flowing to or from the metal surface.

Aqueous solution that contains 1 mole (gram-molecular weight) of solute in 1 L of the solution.

Discontinuities in ci coating (suchasporosity, cracks, gape. and similar Bawd) that allow areas of base metal to be exposed to any corrosive environment that contacts the coated surface.

Heating an alloy to a suitable temperature, holding at that temperature long enough to cause one or more constituents to enter into solid solution, and then cooling rapidly enough to hold these constituents in solution.

Pertains to the machining characteristics of an alloy to which one or more ingredients have been introduced to give small broken chips, lower power consumption, better surface finish, and longer tool life; among such additions are sulfur or lead to steel, ...

See Pourbaix (potential-pH) diagram.

Aging induced by cold working.

Plastic deformation by the irreversible shear displacement (translation) of one part of a crystal relative to another in a definite crystallographic direction and usually on a specific crystallographic plane. Sometimes called glide.

In chemistry,a homogeneous dispersion of two or more kinds of molecular or ionic species. Solution may be composed of any combination of liquids, solids, or gases, but they always consist of a single phase.

The heavy oxide layer formed during hot fabrication or heat treatment of metals.
