Cast-In Straps. Metal (usually steel) sections placed inside sacrificial
anodes during the casting process which are used for attaching the anodes to
the structure to be protected.
Cathodic 1. When used to compare the potentials of two metals or a direction
of change of potential, the more positive.
Cathodic 2. A phenomenon occuring at the cathode of an electrochemical cell
Cathodic Protection. A technique to prevent the corrosion of a metal surface
by making that surface the cathode of an electrochemical cell.
Corrosivity. A measurement of the tendency of an environment to cause
corrosion such as in a high corrosivity soil.
Separation between a coating and substrate.
EFD. Engineering Field Division - An organization within the Naval Facilities
Engineering Command responsible for functions in and located within a specific
Electrochemical. A phenomenon where chemical change occurs through the
indirect exchange of electrons.
Electrogalvanized. Coated with zinc in an electroplating process.
Electrogalvanized zinc coatings are usually much thinner than hot-dip
galvanized zinc coatings.
Electrolyte. A chemical substance or mixture, usually liquid, containing ions
that migrate in an electric field. Usually refers to the soil or liquid ad-
jacent to and in contact with a buried or submerged metallic structure, in-
cluding the moisture or other chemicals contained in it.
Having the shape generated through the rotation of an ellipse.
Materials formed by forcing the material through an orifice or
Flourinated Ethylene Propylene -
An insulating polymer.
Flow-Protective Current. The movement of electrons in an electrical conductor
or ions in an electrolyte which are associated with the cathodic protection of
Attached very close to or touching the surface.
