65 results about "Galvanic anode" patented technology

A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive electrochemical potential) than the metal of the structure. The difference in potential between the two metals means that the galvanic anode corrodes, so that the anode material is consumed in preference to the structure.

Galvanic Panel with Compliant Construction

A prefabricated sacrificial galvanic anode panel includes a rigid or semi-rigid backing board or similar support surface over which a thin layer of cement, mortar or adhesive is applied for holding a compliant layer of material in place on the support surface. The layer of wet adhesive, cement or mortar is sufficiently thin so that upon drying it does not cause warping of the support surface. The compliant or spongy layer is laminated or sandwiched between a thicker layer of ionically conductive galvanic mortar and the substrate support surface. The compliant or spongy layer prevents the thicker layer of galvanic mortar from wetting the backing board or substrate support surface so as to prevent warpage upon drying of the thicker layer of galvanic mortar and also accommodates the expansion of corrosion products from the galvanic anode material.
