See hydrogenembriltlement.

A cracking process that requires the simultaneous action of a corrodent and sustained tensile stress. This excludes corrosion-reduced sections that fail by fast fracture. It also excludes intercrystalline or transcrystalline corrosion, which can disintegr ...

The art of producing metal powders and utilizing metal powders for production of' massive materials and shaped objects.

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

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 component of either a liquid or solid solution that is present to a lesser or minor extent: the component that is dissolved in thesolution.

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

The reaction of a metal or alloy with a sulfur-containing species to produce a sulfur compound that forms on or beneath the surface on the metal or alloy.

A chemical substance or combination of substances that, when present in the environment, prevents or reduces corrosion without significant reaction with the components of the environment.

Formation of isolated particles of corrosion products beneath a metal surface. This results from the prcferential reactions of certain alloy constituents to inward diffusion of oxygen, nitrogen, or sulfur.

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

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.

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

The part of the total carbon in steel or cast iron that is present in elemental form as graphite or temper carbon. Contrast with combined carbon.

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.

Same as bipolar electrode.

When an electrode reaches dynamic equilibrium in a solution, the rate of anodic dissolution balances the rate of cathodic plating. The rate at which either positive or negative charges are entering or leaving the surface at this point is known as the exch ...

Coating containing a zinc powder pigment in an inorganic vehicle.
