Cathodic protection of ships
The amount of stagnant dirty water in the ship's bilge is too small, so conventional anodes cannot provide protection. Experiments have been conducted using conductive adhesives to attach very flat anodes to polished surfaces, but the results showed that this method is not very effective. However, using aluminum or zinc alloy wire anodes with a steel core has yielded better results. These wire anodes have a diameter of 6 to 10 mm and are laid in a ring shape directly on the deck. They pass through fixed structural components and are secured in place with brazing. Sprinkling zinc powder on the relevant areas can increase activity and provide additional protection. Sprinkling 10 to 100 micrometers of zinc powder in corrosion pits can achieve good localized protection, but it is necessary to sprinkle zinc powder regularly, such as every 3 to 6 months. The wire anodes can be used for 2 years after installation.

Introduction to Cathodic Protection Technology
Cathodic protection is one of the most effective methods to prevent electrochemical corrosion of metals.
The applicable scope of local cathodic protection.
The basic principle of commonly used cathodic protection (see section 10.2) is to electrically isolate the protected structure from all devices with low grounding resistance. However, this poses a significant technical challenge in industrial installations due to the large number of pipes and their considerable diameter.
