Abstract

An autonomous impressed current cathodic protection device utilizes a spiral layout of materials, with a magnesium sheet placed in parallel with a copper sheet, and a foamed material in between as insulation, all placed in a plastic container and solidified after inert fluid material is poured in. At a center of the spiral layout, a magnesium anode core is connected through a wire to the surrounding spiral layout. The device can generate electrical voltage of up to −1.7 volt with increased amperage of up to 500 mA. The presented layout of the materials and components allows for increased flexibility concerning the manufacturing of devices based on the requirements of industrial applications, construction sites, and various needs and demands in marine applications for ships, regardless of size.
