Abstract

The invention relates to a sacrificial anode assembly. The sacrificial anode assembly includes a sacrificial anode, an insulator positioned around an end of the anode, an electric coupler positioned around the insulator and extending beyond the end of the anode, the electric coupler electrically isolated from the anode, a resistor having a first lead and a second lead, the first lead electricallyconnected to the anode and the second lead electrically connected to the electric coupler, and a cap positioned around the electric coupler, the cap electrically connected to the electric coupler andelectrically isolated from the anode. The cap complete encapsulates the resistor, the first lead, and the second lead.

Description

Background technique [0001] Corrosion is an electrochemical process involving the anode, electrolyte and cathode. When a piece of metal corrodes, the electrolyte provides charged hydrogen ions and hydroxide molecules to the metal. Corrosion occurs when charged hydroxide ions combine with the metal, producing metal hydroxides that precipitate the metal into the electrolyte. Through this reaction, electrons are released into the metal. As hydrogen ions flow through the electrolyte to the cathode, an equilibrium cathodic reaction also occurs, releasing electrons from the metal and forming hydrogen gas. These reactions involve the transfer of charges, so that the total number of electrons released by corrosion of steel and aluminum (anodic reaction) must be consumed by hydrogen evolution (cathodic reaction). [0002] Implement cathodic protection systems in water heaters to stop corrosion of the water heater tank. The cathodic protection system includes an anode rod electrical...
