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.

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

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

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

The technique for maintaining a constant electrode potential.

Aging induced by cold working.

See hydrogen embrittlement.

Through or across crystals or grains. Also called intracrystalline or transcrystalline.

Reduction in mechanical properties of a metal as a result of local penetration of solder along grain boundaries.

Cracking or fracturing that occurs between the grains or crystals in a polycrystalline aggregate. Also called intercrystalline cracking. Contrast with transgranular cracking.

The component of either a liquid or solid solution that is present to a greater or major extent; the component that dissolves the solute.

Electrode potential where half-cell reaction involves only the metal electrode and its ion.

See galvanostatic.

Deep internal cracks caused by hydrogen.

In fatigue, the variation in the stress-intensity factor in cycle, that is, Kmax-Kmin.

Corrosive attack that progresses preferentially along interdendritic paths. This type of attack results from local differences in composition, such as coring commonly encountered in alloy castings.

See hydrogenembriltlement.

The ability of a metal to absorb energy and deform plastically before fracturing.

See intergranular corrosion.

A plot of r urrent density versus electrode potential for a specific electrode-electrolyte combination.
