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 Risk of Using Galvanized A325 Bolts in Corrosion-Resistant Steel Bridges
Journal of Bridge Engineering, 2019This experimental study was the first to evaluate the galvanic corrosion risk of using galvanized ASTM A325 Type I bolts with ASTM A1010 steel girders in the construction of A1010 steel bridges. The emerging construction of A1010 steel bridges is intended to extend the service life of bridges and reduce the need for maintenance under atmospheric ...

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 ...

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.

Polarization Effects in Galvanic Corrosion
Corrosion, 1986Galvanic corrosion In couples of AISI 304 stainless steel (SS), Ferralium(1) Alloy 255, Hastelloy(1) Alloys B-2 and G-3, grade 2 titanium, and graphite was examined in boiling 10% sulfuric and ambient-temperature hydrochloric acids. The galvanic corrosion rates were determined by measurement of the galvanic current using (1) a zero resistance ammeter ...

Effect of Titanium in Galvanic Corrosion
Corrosion, 1952While titanium has remarkable corrosion resistance in many environments, other factors have to be considered before this metal can be used in naval aircraft construction as a replacement for stainless steels. Among these are galvanic effects which could result from contact with dissimilar metals in marine, atmospheres.
