Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.
Bimetallic strips and disks, which convert a temperature change into mechanical displacement, [1] are the most recognized bimetallic objects due to their name. However, there are other common bimetallic objects. For example, tin cans consist of steel covered with tin. [2] The tin prevents the can from rusting.
Galvanic corrosion is the electrochemical erosion of metals. Corrosion occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte , such as salt water. This forms a galvanic cell, with hydrogen gas forming on the more noble (less active) metal.
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by ...

A bimetallic strip is used to compensate this phenomenon in the mechanism of some timepieces. The most common method is to use a bimetallic construction for the circular rim of the balance wheel. What it does is move a weight in a radial way looking at the circular plane down by the balance wheel, varying then, the momentum of inertia of the ...
Bimetallic or bi-metallic may refer to: Bimetallism, a monetary standard in economics; Bimetallic strip, a temperature sensitive mechanical device; Alloy (binary alloy), in metallurgy, a mixture of two metals; Bi-metallic coin; Bi-Metallic Investment Co. v. State Board of Equalization
Bimetallic corrosion. Galvanic corrosion (also called bimetallic corrosion) is an electrochemical process in which one metal (more active one) corrodes preferentially when it is in electrical contact with another dissimilar metal, in the presence of an electrolyte.
