Preventing selective leaching involves several strategies:
- Alloy Modification: Using alloys specifically designed to resist leaching, such as dezincification-resistant brass.
- Protective Coatings: Applying coatings to the metal surface to act as a barrier against corrosive agents.
- Corrosion Inhibitors: Adding chemicals to the environment that slow down or prevent the leaching process.
- Environmental Control: Reducing exposure to aggressive chemicals through proper design and maintenance of systems.
- Cathodic Protection: Applying a small electrical charge to counteract the electrochemical reactions that lead to selective leaching.
These measures help maintain the integrity and longevity of metal components in corrosive environments.
