Coating containing a zinc powder pigment in an inorganic vehicle.

The binding of an adsorbate to the surface of a solid by forces whose energy levels approximate those of condensation. Contrast with chemisorption.

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.

Molten slag; in the pulp and paper industry, the cooking chemicals tapped from the recovery boiler as molten material and dissolved in the smelt tank as green liquor.

Resin formed by condensation of polybasic and monobasic acids with polyhydric alcohols.

The technique for varying the potential of an electrode in a continuous manner at a preset rate.

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

Corrosion occurring preferentially at grain boundaries, usually with slight or negligible attack on the adjacent grains. Also called intercrystalline corrosion.

A specimen that is notched and subjected to alternating stresses until a crack has developed at the root of the notch.

A tendency for some alloys to separate along grain boundaries when stressed ordeformed at temperatures near the melting point.Hot shortness is caused by a low-melting constituent, often present only in minute amounts,that is segregated at grain boundaries ...

A chain of organic molecules produced by the joining of primary units called monomers.

A metallic coating obtained bydipping the base metal into a molten metal.

An aggregate of iron or alloy carbides of essentially spherical shape dispersed throughout a matrix of ferrite.

A buried item, such as junk steel or graphite rods, that serves as the anode for the cathodic protection of pipelines or other buried structures. See also deep groundbed.

Perforation of material in outer space resulting from meteor strikes.

The intensity of the internally distributed forces or components of forces that resist a change in the volume or shape of a material that is or has been subjected to external forces. Stress is expressed in force per unit area and is calculated on the basi ...

Corrosion that proceeds laterally from the sites of initiation along planes parallel to the surface, generally at grain boundaries, forming corrosion products that force metal away from the body of the material, giving rise to a layered appearance.

See hydrogen embrittlement.

The formation of isolated particles of corrosion products beneath the metal surface. This occurs as the result of preferential oxidation of certain alloy constituents by inward diffusion of oxygen, nitrogen, sulfur, and so forth.

The swelling or bubbling of a coating usually because of heating (term currently used in space and fire protection applications).
