Effect of Sacrificial Anode Power Dissipation on Its Anode Life

Studies have been carried out to investigate the effect of sacrificial anode power dissipation on its anode life. The results of the investigation show that decrease in the power dissipated by the sacrificial anode during the discharge of current, increases the anode life. This resulted from the fact that decrease in the power dissipation implies increased resident energy of the sacrificial anode hence, the greater the length of time the sacrificial anode can perform its protective function. It was also found that increase in the electrical resistance of the sacrificial anode increases the anode life. This results from reduction in the discharged current and minimization of power dissipation. (Report and Opinion. 1010;2(1):94-97). (ISSN: 1553-9873).
