  2. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    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 ...

  3. Galvanic series - Wikipedia

    en.wikipedia.org/wiki/Galvanic_series

    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 ...

  4. List of brazing alloys - Wikipedia

    en.wikipedia.org/wiki/List_of_brazing_alloys

    Near-eutectic. Same applications as BAg-1. Suitable for most metals, e.g. steel, stainless steel, copper, nickel and their alloys. Unsuitable for aluminium and magnesium. For ferrous, nonferrous and dissimilar alloys. Narrow melting range, no liquation. High fluidity, for close joint clearances.

  5. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    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.

  7. Galvanic anode - Wikipedia

    en.wikipedia.org/wiki/Galvanic_anode

    A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive oxidation potential ) than the metal of the structure.
