An accelerated corrosion test for electrodeposits.

The chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.

A change in any part of the corrosion system caused by corrosion.

The severe loss of ductility of a metal resulting from corrosive attack, usually inter,granular and often not visually apparent.

The process in which a metal fractures prematurely under conditions of simultaneous corrosion and repeated cyclic loading at lower stress levels or fewer cycles than would be required in the absence of the corrosive environment.

The maximum cyclic stress value that a metal can with stand for a specified number of cycles or length of time in a given corrosive environment. See corrosion fatigue strength

The maximum repeated stress that can he endured by a metal without failure under definite conditions of corrosion and fatigue and for a specific number of stress cycles and a specified period of time.

See inhibitor

The potential of a corroding surface in an electrolyte, relative to a reference electrode. Also called rest potential, open circuit potential, or freely corroding potential.

Substance formed as a result of corrosion

Modification of a corrosion system so that corrosion damage is mitigated.

Corrosion effect on a metal per unit of time. The type of corrosion rate used depends on the technical .system and on the type of corrosion effect. Thus, corrosion rate may be expressed as an increase in corrosion depth per unit of time (penetration rate, ...

Ability of a metal to withstand corrosion in a given corrosion system.

System consisting of one or more metals and all parts of the environment that influence corrosion.

Corrosion which is increased because of the abrasive action of a moving stream; the presence of suspended particles greatly accelerates abrasive action.See erosion-corrosion.

Tendency of an environment to cause corrosion in a given corrosion system.

See auxiliary electrode.

A cell developed in an electrolyte resulting from electrical contact between two dissimilar metals. See galvanic corrosion.

The ability of a solution to give satisfactory plating at very low current densities. a condition that exists in recesses and pits. This term suggests an ability to cover, but not necessarily to build up, a uniform coating, whereas throwing power suggests ...

Breaks in a coating that extend through to the underlying surface.
