Dissimilar metals and alloys have different electrode potentials, and when two or more come into contact in an electrolyte, one metal (that is more reactive) acts as anode and the other (that is less reactive) as cathode. The electropotential difference between the reactions at the two electrodes is the driving force for an accelerated attack ...
The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in ...
This page lists metals, with subdivisions for alloys and specialised subsets of metal and metal-based compounds. Subcategories This category has the following 19 subcategories, out of 19 total.
Metals comprise the large majority of the elements, and can be subdivided into several different categories. From left to right in the periodic table, these categories include the highly reactive alkali metals ; the less-reactive alkaline earth metals , lanthanides , and radioactive actinides ; the archetypal transition metals ; and the ...
Free-flowing, most fluid of aluminium filler metals. General purpose filler metal, can be used with brazeable aluminiums in all types of brazing. For joining aluminium and its alloys. Can be used for joining aluminium and titanium to dissimilar metals; the risk of galvanic corrosion then has to be considered.
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The electric potential outside each material is controlled by its work function, and so dissimilar metals can show an electric potential difference even at equilibrium. The Volta potential is not an intrinsic property of the two bulk metals under consideration, but rather is determined by work function differences between the metals' surfaces ...
