Corrosion that occurs when two metals are in contact with each other and with water.
Electrochemical corrosion associated with current in a galvanic cell, which is set up when two dissimilar metals (or the same metal in two different metallurgical conditions) are in electrical contact and are immersed in an electrolytic solution.
a type of corrosion that occurs when a small electric current flows from one piece of metal equipment to another. It is particularly prevalent when two dissimilar metals are present in an environment in which electricity can flow (as two dissimilar joints of tubing in an oil or gas well).
Deterioration of a metal caused by the electric current produced when two unlike metals are in contact under certain condition.
A condition caused as a result of a conducting liquid making contact with two different metal which are not properly isolated physically and/or electrically.
Galvanic corrosion can occur when different metals are in metallic contact with each other, at the same time that there is a continuous electrolyte bridge between the metals. Ordinarily the more ignoble metal corrodes and the most noble is protected against corrosion. Aluminium is often the most ignoble metal and consequently the risk for corrosion is greater than for most other construction material.
Self-induced current created by electrical potential of two dissimilar metals in contact with an electrolyte.
Accelerated corrosion of a metal because of an electrical contact with a more noble metal or nonmetallic conductor in a corrosive electrolyte.
Corrosion which occurs between two dissimilar metals in the presence of moisture or some other electrolyte. Under these conditions, an electrochemical cell is formed and current will flow from one metal to the other carrying tons of the metal with it. Compare Electrolytic Corrosion.
Dissimilar metals in contact with each other in presence of moisture, acting as a battery and causing an electrolytic etching deteriorating effect.
The action of an electric current generated by two different metals in close proximity with the presence of water, resulting in corrosion of the less noble metal.
Corrosion associated with the current of a galvanic cell made up of dissimilar electrodes.
Corrosion associated with the current of a galvanic cell consisting of two dissimilar conductors in an electrolyte or two similar conductors in dissimilar electrolytes; where the two dissimilar metals are in contact, the resulting reaction is referred to as couple action.
A type of corrosion which is caused by an electric current flowing between two dissimilar alloys or metals which come into contact with each other. Under these circumstances, the more reactive metal or alloy corrodes while the less reactive metal is protected. For example, if iron and copper were in direct physical contact in the presence of moisture and oxygen, the iron would selectively corrode while simultaneously protecting the copper.
Electrical flow or chemical interaction caused by dissimilar materials (usually metal).
Corrosion in a metal caused by a galvanic cell created by dissimilar metals in close proximity accompanied by an electrolyte, often atmospheric moisture; also called Galvanic Action.
The erosion resulting from electrical current flow from a noble metal (anode) to a less noble metal (cathode).
A form of corrosion which occurs in a galvanic cell in which one of the metals dissolves and goes into solution.
The form of corrosion which occurs in a galvanic cell, in which one of the metals goes into solution; accelerated by high concentrations of dissolved minerals in water, which increases the electrical conductance; and elevated temperatures. (See corrosion, electrolyte.)
