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