FIG. 1.

Wetting and corrosion test using pure water droplet for the pristine (a), (b), and (c) MWNTs-reinforced magnesium alloy composites. Left row shows the samples ( diameter) after , and middle row shows the samples after . Difference in the number of bubbles among the samples can be clearly seen as bright spots (as indicated by short red arrow). Wetting angles have changed from 20° to 32° for pristine and MWNTs-reinforced magnesium alloy composites. After , the surfaces are similarly corroded, but in the pristine magnesium alloy (a), bubbles were still coming out (short blue arrow). Right column shows the optical micrograph of the vertical section that was obtained by cutting the samples along the dotted line shown in the middle images. Green dotted line shows the edge between the section and the surface of the composite. Black arrow shows the pitting formed as worm-eaten holes.

Corrosion current of pristine and MWNTs-reinforced magnesium alloy composites in tap water (, 8.05).

FIG. 4.

FE-SEM images exhibiting the surface morphologies of the pristine and MWNTs-reinforced magnesium alloy composites, respectively. The pristine magnesium alloy has more cracks compared to MWNTs/magnesium alloy composite. As shown in the right image, we can find the MWNT reinforcing the oxide layer.
