How to prevent selective leaching?

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.
