Abstract A novel Zn-22Al-Mg-Re alloy coating was prepared on Q420 steel substrate by arc spraying technology, and the microstructure, adhesive strength and corrosion resistance of the coating were characterized by SEM, copper accelerated acetic acid salt spray test (CASS) and electrochemical measurement in comparison with Zn and Zn-15Al coating. The results show that, the Zn-22Al-Mg-Re coating exhibits lower passivation potential with lower passivation current, because of its ability to form a very stable, adherent, small acicular, well self-sealing protective corrosion products film, the cathodic protection effectiveness and corrosion resistance of Zn-22Al-Mg-Re coating is better than Zn, Zn-15Al coating.

Key words: Zn-22Al-Mg-Re bonding strength self-sealing corrosion resistance
