  • Us5040599a - Cathodic Protection - Google Patents

    Cathodic corrosion protection of a metallic structure in contact with the earth employs a backfill material which is a mixture of a carbonaceous solid and a clay. The backfill mixture is used to fill around at least one anode which is positioned in a borehole in the earth. A DC voltage is applied to the metallic structure and anode to provide the corrosion protection.

  • Natural Deposit Coatings On Steel During Cathodic ...

    The calcareous coating formed during cathodic protection CP in seawater is known to reduce the current demand by hindering the transport of species required to support the cathodic reactions and, thereby, improve the economic performance of CP systems. There is, however, uncertainty as to whether the coating reduces hydrogen uptake or indeed enhances it. To ascertain this, two sets of ...

    These anodes should be buried deep in the ground a certain distance away from the structure it protects. A groundbed cathodic protection system is a low-cost and highly effective option, since various components like tanks, pipes, fuel pumps, wirings and others need not be interrupted. All that is needed is a deep hole for the anodes.

  • Understanding Corrosion And How To Protect Against

    Protection from rust by sacrificial metals is commonly used in several forms Zinc or magnesium blocks are often used to protect ship hulls, water tank interiors and other submerged surfaces. Complete covering of the steel with the sacrificial metal is often done. Galvanized steel, for example, is steel covered with zinc.
