Abstract

The present work provides a one-step method of encapsulating a corrosion inhibitor, NaVO3, relevant to protection of AA2024-T3, into hollow microparticles. By dispersing these microparticles into a PVB coating, the encapsulated NaVO3 may be continuously released into the electrolyte and heal the corroded sites spontaneously. The improvement of corrosion inhibition by NaVO3 microencapsulation described herein was validated by electrochemical methods and salt spray/immersion test.
