✦ Synopsis

The present paper studies the effect of different treatments with tanmc, galhc and phosphonc aads, which are applied on a rusted steel surface for stahhzmg the rust layer before a paint coatmg IS applied Impedance, polanzatlon resistance and chemical analysis data suggest that none of the apphed treatments effectively block the actlvtty In the rusted steel surface
