Relating to electrochemistry; that is, having to do with the relationship of chemical changes and electric forces.

1. A device that converts chemical energy into electrical energy by passing current between a negative electrode and a positive electrode, through an ionically conducting electrolyte phase.

Relating to or containing matter in the form of charged atoms or groups of atoms.

2. A device containing two conducting electrodes, one positive and the other negative, made of dissimilar materials (usually metals) that are immersed in a chemical solution (electrolyte) that transmits positive ions from the negative to the positive electrode and so forms an electrical charge.

One or more cells result in a battery.

The mass of a substance reacting when a specified quantity of electric charge is passed during electrolysis.

1. Removing excess metal by electrolytic dissolution, effected by the tool acting as the cathode against the workpiece acting as the anode.
2. An electrochemical process, similar to electroplating, in which the workpiece acts as an anode and the tool as a cathode.
3. A metal-cutting process that is the reverse of electroplating.

A low DC voltage is applied between the workpiece and a tool having the shape of the desired cut, and saltwater or some other electrolyte is pumped at high pressure through the gap between the workpiece and the tool.

Electrochemical action in the gap erodes metal from the workpiece.

4. A process to produce metallic objects with a technique that is essentially precision electrodissolution (dissolving of a substance from an electrode by electrolysis).

One of the advantages of this production technique is that very complicated shapes can be produced with a single operation from very hard alloys that would be very difficult, if not impossible, to machine with any other metal cutting technique.

Some typical applications are the production of turbine blades and the drilling of holes with very large depth-to-diameter ratio.

1. A combined grinding and machining operation in which the abrasive cathodic grinding wheel is in contact with the anodic surface or an electrode from which electrons leave an electrolyte.

Used with a metal-bonded and diamond-impregnated grinding wheel.

2. A combined grinding and machining operation in which the abrasive, cathodic grinding wheel is in contact with the anodic work piece beneath the surface of an electrolyte.

1. The classification of metals in the order of their electrode potentials.
2. A serial arrangement of metallic elements or ions according to their electrode potentials determined under specified conditions; the order shows the tendency of one metal to reduce the ions of any other metal below it in the series.
3. A series in which the metals and other substances are listed in the order of their chemical reactivity or electrode potentials, the most reactive at the top and the less reactive at the bottom.
4. A tabulation on which various substances; such as, metals or elements, are listed according to their chemical reactivity or standard electrode potential.

It is usually ordered with increasing standard electrode potentials (most negative on top).

For metals, the order indicates the tendency to spontaneously reduce the ions of any other metal below it in the series.

During electrolytic reduction of cations (for example, electroplating) an element lower in the series (more positive) will deposit first, and an element higher in the series (more negative) will deposit only when the solution is practically depleted of the ions of the first element.
