  Adhesion - The attractive force that exists between an electrodeposit and its substrate that can be measured as the force required to separate
an electrodeposit and its substrate.

Anode - The electrode in electrolysis at which negative ions are discharged, positive ions are formed, or other oxidizing reactions occur.

Barrel Plating - Electroplating of small parts in bulk in a rotating container.

Basis Metal - Metal upon which coatings are deposited.

Bridging - The formation of a conductive path between conductors.

Bright Dip - A solution used to produce a bright surface on a metal.

Bright Plating - A process that produces an electrodeposit having a high degree of specular reflectance in the as-plated condition.

Cathode - The electrode in electrolysis at which positive ions are discharged, negative ions are formed, or other reducing reactions occur.

Chromate Conversion - A coating produced by chemical or electrochemical treatment of a Coating - metallic surface that gives a superficial layer containing compounds of the metal and the chromium constituents of the processing solution.

Coloring - (1) The production of desired colors on metal surfaces by chemical or electrochemical action. (2) Light buffing of polished metal surfaces for the purpose of producing a high luster.

Conversion Coating - A coating produced by chemical or electrochemical treatment of a metallic surface that gives a superficial layer containing
a compound of the metal.

Corrosion - (1) Gradual solution or oxidation of a metal. (2) Solution of anode metal by the electrochemical action in the plating cell.

Covering Power - The ability of a plating solution under a specified
set of plating conditions to deposit metal on the surfaces of recesses or deep holes. (Distinguished from throwing power).

Dewetting - A condition which results when the molten solder has coated
the surface and then receded, leaving irregularly shaped mounds of solder separated by areas covered with a thin solder film without exposing the basis metal. Dewetting may be caused by electrodeposits of tin or solder that are too heavy.

Drag-Out - The solution that adheres to articles removed from a processing tank.

Electrolysis - Production of chemical changes by the passage of current through an electrolyte.

Electrolyte - (1) A conducting medium in which the flow of current
is accompanied by movement of matter. Most often an aqueous solution
of acids, bases, or salts, but includes many other media, such as fused salts, ionized gases, some solids, etc. (2) A substance that is capable
of forming a conducting liquid medium when dissolved or melted.

Electroplating - The electrodeposition of an adherent metallic coating upon an electrode for the purpose of securing a surface with properties or dimensions different from those of the basis metal.
