Coating containing a zinc powder pigment in an inorganic vehicle.

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

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.

Ferrire that is formed directly from the decomposition of hypoeutectoid austenite during cooling, without the simultaneous formation of cementite. Also called proeutectoid ferrite.

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.

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

A metal whose luster has been reduced because of a surface film, usually a corrosion product layer.

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.

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

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

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

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

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.

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 ...

Ratio of the depth of the deepest pit resulting from corrosion divided by the average penetration as calculated from weight loss.

Resin formed from reactions involving furfuryl alcohol alone or in combination with other constituents.

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.

The liquor resulting from dissolving molten melt irom the kraft recovery furnace in water. See also kraft process and smelt.
