Corrosion engineering

natural aging

Materials science; Corrosion engineering

Spontaneous aging of a supersaturated solid solution at room temperature.

conductivity

Materials science; Corrosion engineering

The ratio of the electric current density to the electric field in a material. Also called electrical conductivity or specific conductance.

current efficiency

Materials science; Corrosion engineering

The ratio of the electrochemical equivalent current density for a specific reaction to the total applied current density.

relative humidity

Materials science; Corrosion engineering

The ratio, expressed as a percentage, of the amount of water vapor present in a given volume of air at a given temperature to the amount required to saturate the air at that temperature.

sulfidation

Materials science; Corrosion engineering

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.

polarization admittance

Materials science; Corrosion engineering

The reciprocal of polarization resistance (di/dE).

The region of an anodic polarization curve, noble to and; above the passive potential range, in which there is a significant increase in current density (increased metal dissolution) as the potential ...
