| Résumé : | Carbon nanotubes (CNTs) have been demonstrated as good reinforcements to improve mechanical properties of magnesium alloys. This study reports on the influence of CNT dispersion on corrosion behaviour of their Mg composites. Experiments revealed that the corrosion rate is drastically increased by adding CNTs to the magnesium alloy due to galvanic coupling. Moreover, a homogeneous CNT dispersion leads to reduced corrosion resistivity. Surface pre-treatment is also found to be critical for the corrosion performance for both 1 and 5 wt% CNT composites. |
