Galvanic and Deposition Corrosion
Materials Performance, 2023Corrosion engineers are familiar with the galvanic series,1 which lists “noble” and “active” metals, and with galvanic corrosion— often referred to as two-metal or dissimilar-metal corrosion. They may well have encountered examples of galvanic corrosion during their field or plant work.

Galvanic Corrosion Risk Mapping
Corrosion, 2019Galvanic corrosion is a major problem impacting aerospace platform design, retrofit, and maintenance. MIL-STD-889 provides guidance on dissimilar material selection based on the corrosion potential of materials in flowing seawater. This standard provides a general guide for materials selection, but contains a limited material database and does not ...

Atmospheric Galvanic Couple Corrosion
Corrosion, 1955Tests designed to provide fundamental information explaining the behavior of galvanic couples in the atmosphere are reported. The purpose is to permit prediction of their probable relative behavior. Measurements of weight losses of couples in a marine, an industrial and a severe tropical atmosphere are reported.Tests involving thin sheet electrode ...

Galvanic corrosion of selected dental alloys
Journal of Oral Rehabilitation, 2001Samples prepared from three different amalgam brands were coupled to two gold alloys and orthodontic brackets. In the resulting galvanic cells, the amalgam coupled to gold were anodic, exhibiting galvanic current densities about one order of magnitude higher than the uncoupled corrosion current densities of 0·2–0·5 μA.

Galvanic Corrosion on Automobiles
1988Automobile manufacturers utilize a variety of metals to build a product that meets numerous functional and cosmetic demands. Since the auto environment is highly corrosive, they must consequently deal with galvanic corrosion problems. This paper describes some of the galvanic couples on automobiles, such as trim on painted auto-body steel, dissimilar ...

Two dissimilar metals, A and C, subject to corrosion in the same electrolyte, normally are at different corrosion potentials, (ea)corr and (ec)corr. The electrode system metal C/solution/metal A then is a galvanic cell with the open-circuit voltage $$ \Delta \varepsilon = (\varepsilon _c )_{corr} - (\varepsilon _a )_{corr} $$ (11.1) We choose

Galvanic Corrosion of Aluminum
Corrosion, 1979Laboratory tests were carried out to compare the electrochemical characteristics of galvanic couples made of aluminum alloys (1050, 5086, 2024, and 7075) with other metals (plain steel, Type 316 stainless steel, titanium) in tap water and in artificial sea water.

Galvanizing — economical corrosion protection
Anti-Corrosion Manual, 1987Substantial savings in protection costs can be achieved with greater use of hot dip galvanizing. Brian Lansley, marketing manager at the Galvanizers Association discusses the economic benefits offered by galvanizing over other corrosion protection systems.

Galvanic Corrosion Caused by Corrosion Products
1988Experiments were conducted to quantify the magnitude of galvanic currents and potentials that exist between metals (iron, copper, titanium, aluminum, chromium, and nickel) and their corrosion products in oxygen-containing environments. Current measurements using a zero resistance ammeter and potential measurements of metal electrodes and oxide ...
