Simulation study on anti-corrosion performance of a ferroalloy flange

Abstract The corrosion problem of seawater pipeline is an important problem that ships need to face. Installing anticorrosive zinc block in seawater pipeline is a simple and practical anticorrosion means. In this paper, the anti-corrosion performance of a ferroalloy flange is simulated and analysed. The results show that, for the copper pipeline, both cathode current and anode current of the seawater pipeline using the copper - ferroalloy anticorrosive mode are significantly lower than those of the seawater pipeline using the copper - zinc alloy anticorrosive mode under the same external environment. This means that the anticorrosion performance of copper - ferroalloy model is obviously better than that of copper - zinc alloy model.
