Abstract 

The protective performance of polyaniline/epoxy coating was effectively improved by adding appropriate tephra micron particles (TMP). Meanwhile the effect of TMP incorporation content on protective efficiency was investigated. The experiment results indicate that impedance modulus of low frequency for coatings with TMP maintained high levels after 60 days immersion in NaCl solution (95℃, 12%). Among them coating with 10% TMP had the highest impedance modulus, 1.27×109 Ω·cm2, which means the coating steel had a well protective performance. In addition, the hybrid coating has improved adhesion strength and outstanding thermal shock resistance.
