Comparison and Analysis of Zinc Anode Materials for Marine Corrosion protection Zinc anode for Marine corrosion protection zinc anode protection method refers to that in corrosive medium, when the ship corrosion protection zinc anode forms an electrical connection with the protected metal, as the ship corrosion protection zinc anode metal by itself dissolves and releases the current to polarize the protected metal component - cathode to the protection potential and realize the metal corrosion prevention method. The effect of Marine anticorrosive zinc anode for cathodic protection is directly related to the properties of anode material. Marine anticorrosive zinc anode material should have the following properties: (1) have enough negative potential; (2) working anode polarizability is small, the dissolution is uniform, the product can automatically fall off; (3) High current efficiency; ④ High electrochemical equivalent; ⑤ The corrosion products are non-toxic and do not pollute the environment; ⑥ Cheap price, convenient source, easy to process. At present, there are magnesium base alloy, zinc base alloy and aluminum base alloy which are commonly used in Marine anticorrosive zinc anode materials. Due to the different composition and electrochemical properties of materials, the application environment is also different.
