Cover: The main image was taken by optical microscopy and shows a polished 0.1 wt% well‐dispersed MWCNT/AZ91 sample after 1 day immersion in 3.5% NaCl. The inset presents a SEM image of pristine MWCNTs, which we postulate to act as electrodes in the AZ91 composites. The evenly distributed corrosion pattern in the main image indicates that with well‐dispersed MWCNTs in AZ91, formation of galvanic couples takes place everywhere on the composite surface. The corrosion rate of the AZ91 composites with well dispersed MWCNTs is therefore strongly increased compared to the composites with less well dispersed MWCNTs and pure AZ91.
