An oil capable of conversion from a liquid to a solid by slow reaction with oxygen in the air.
Fracture characterized by tearing of metal accompanied by appreciable gross plastic deformation and expenditure of considerable energy. Contrast with brittle fracture.
The ability of a material to deform plastically without fracturing, measured by elongation or reduction of area in a tensile test, by height of cupping in an Erichsen test, or by other means.
(1) A cathode, usuully corrugated to give variable current densities, that is plated at low current densities to preferentially remove impurities from a plating solution. (2) A substitute cathode that is used during adjustment of operating conditions.
Plating with dummy cathodes.
The condition of an electrode when the rate of anodic dissolution just balances the rate of cathodic plating.885
A change in dimensions directly proportional to and in phase with an increase or decrease in applied force.
The maximum stress that a material is capable of sustaining without any permanent strain (deformation) remaining upon complete release of the stress.
The property of a material by virtue of which deformation caused by stress disappears upon removal of the stress. A perfectly elastic body completely recovers its original shape and dimensions after release of stress.
A natural or synthetic polymer, which at room temperature can be stretched repeatedly to at least twice its original length, and which after removal of the tensile load will immediately and forcibly return to approximately its original length.
The condition of being electrically separated from other metallic structures or the environment.
The electrical resistance offered by a material to the flow of current, times the cross-sectional area of current flow and per unit length of current path; the reciprocal of the conductivity. Also called resistivity or specific resistance.
The inverse of electrochemical impedance.
Corrosion that is accompanied by a flow of electrons between cathodic and anodic areas on metallic surfaces.
The weight of an element or group of elements oxidized or reduced at 100~ efficiency by the passage of a unit quantity of electricity. Usually expressed as grams per coulomb.
The frequency-dependent complex-valued proportionality factor (A
The partial derivative of the total electrochemical free energy of a constituent with respect to the number of moles of this constituent where all factors are kept constant. It is analogous to the chemical potential of a constituent except that it include ...
Same as electromotive force series.
Change of electrode potential with respect to a reference value. Often the free corrosion potential is used as the reference value. The change may be caused, for example, by the application of an external electrical current or by the addition of an oxidan ...
