Title: AUTONOMOUS IMPRESSED CURRENT CATHODIC PROTECTION DEVICE ON METAL SURFACES WITH A SPIRAL MAGNESIUM ANODE
Abstract:
This modification refers to a spiral formation layout of materials, with magnesium sheets placed in parallel with a copper sheet and foamed material (4, 6, 7 and 8) in between as insulation, all placed in a plastic container(2) and solidified after inert fluid material (11) is poured in. In the center of the spiral, a magnesium anode rod (core) is connected through a wire to the surrounding spiral. This modified layout replaces the manufacturing process of the previous devices as described in the Diploma Number 1007131. The new device can generate electrical voltage of up to -1, 7 volt as before but with increased amperage of up to 500mA. 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 the various needs and demands in marine applications for ships, regardless of size.
