PAINT ADHESION FAILURE MECHANISMS ON STEEL IN CORROSIVE ENVIRONMENTS

THE CAUSES AND MECHANISMS OF PAINT ADHESION FAILURE ON STEEL, AS A RESULT OF THE CORROSION PROCESSES WITH AND WITHOUT A CONVERSION COATING, HAVE BEEN INVESTIGATED. ELECTROCHEMICAL TECHNIQUES WERE USED TO SEPARATE THE CORROSION REACTIONS AND STUDY THEIR SEPARATE AND COMBINED EFFECTS AT A DISCONTINUITY (SCRIBE LINE) IN THE PAINT FILMS. FOR OPTIMUM CORROSION PROTECTION THE CONVERSION COATING SHOULD RETARD ANODIC UNDERCUTTING AND BOTH THE CONVERSION COATING AND PAINT SYSTEMS SHOULD BE RESISTANT TO HYDROXIDE, PRODUCED BY THE CATHODIC REACTION. /AUTHOR/
