Aluminium

Aluminium (Aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13.

See Galvanic anode and Aluminium

Cathodic protection

Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. Galvanic anode and Cathodic protection are corrosion prevention.

See Galvanic anode and Cathodic protection

Corrosion

Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. Galvanic anode and Corrosion are Electrochemistry.

See Galvanic anode and Corrosion

Electric current

An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space.

See Galvanic anode and Electric current

Enthalpy of sublimation

In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP).

See Galvanic anode and Enthalpy of sublimation

Galvanic corrosion

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.

See Galvanic anode and Galvanic corrosion

Galvanic series

The galvanic series (or electropotential series) determines the nobility of metals and semi-metals.

See Galvanic anode and Galvanic series

Ground (electricity)

In electrical engineering, ground or earth may be a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.

See Galvanic anode and Ground (electricity)

Hydrogen embrittlement

Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Galvanic anode and hydrogen embrittlement are Electrochemistry.

See Galvanic anode and Hydrogen embrittlement

Iron(II) hydroxide

Iron(II) hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH)2.

See Galvanic anode and Iron(II) hydroxide

Magnesium

Magnesium is a chemical element; it has symbol Mg and atomic number 12.

See Galvanic anode and Magnesium

Parts-per notation

In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction.

See Galvanic anode and Parts-per notation

Passivation (chemistry)

In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. Galvanic anode and passivation (chemistry) are corrosion prevention.

See Galvanic anode and Passivation (chemistry)

Redox

Redox (reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Galvanic anode and Redox are Electrochemistry.

See Galvanic anode and Redox

Reduction potential

Redox potential (also known as oxidation / reduction potential, ORP, pe, E_, or E_) is a measure of the tendency of a chemical species to acquire electrons from or lose electrons to an electrode and thereby be reduced or oxidised respectively.

See Galvanic anode and Reduction potential

Thermite

Thermite is a pyrotechnic composition of metal powder and metal oxide.

See Galvanic anode and Thermite

Voltage

Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points.

See Galvanic anode and Voltage

Zinc

Zinc is a chemical element with the symbol Zn and atomic number 30.

See Galvanic anode and Zinc
