Corrosion engineering
Open-circuit potential
Materials science; Corrosion engineering
The potential of an electrode measured with respect to a reference electrode or another electrode when no current flows to or from it.
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.
Natural ageing
Materials science; Corrosion engineering
Spontaneous ageing of a supersaturated solid solution at room temperature.
Transpassive region
Materials science; Corrosion engineering
The region of an anodic polarisation 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 ...
Current efficiency
Materials science; Corrosion engineering
The ratio of the electrochemical equivalent current density for a specific reaction to the total applied current density.
Sulfidation
Materials science; Corrosion engineering
The reaction of a metal or alloy with a sulfur-containing species to produce a sulphur compound that forms on or beneath the surface on the metal or alloy.
Relative humidity
Materials science; Corrosion engineering
The ratio, expressed as a percentage, of the amount of water vapour present in a given volume of air at a given temperature to the amount required to saturate the air at that temperature.
