Abstract Multi-walled carbon nonotubes (MWCNTs) /AZ31 composites were fabricated by joining preform of MWCNTs during melting. The corrosion behaviors of the composites were studied by electrochemical corrosion experiments in 3.5% (mass fraction) NaCl solution. The surface morphologies of the composites before and after corrosion were observed and analysised by SEM. The results showed that additions of MWCNTs improved anticorrosive performances of AZ31 Mg-based alloy, the corrosion current density (I_corr) decreased from 5.279 to 2.994 μA/cm².

Key words: multi-walled carbon nonotubes (MWCNTs) AZ31 magnesium alloy composite
