摘要：

The present study investigated the tribocorrosion behaviour of aluminium/alumina composite produced by accumulative roll bonding process during various cycles of processing. Tribocorrosion tests were performed using a ball-on-plate tribometer, where the sliding contact was fully immersed in 1 wt-% NaCl solution. The sample served as a working electrode, whose open circuit potential was monitored before, during and after sliding. Electrochemical impedance spectroscopy was used to characterise the electrochemical behaviour of the surfaces before and after the sliding wear test. The influence of Al2O3 particle distribution in the aluminium matrix on open circuit potential and electrochemical impedance spectroscopy was evaluated. It was found that the dispersion of alumina particles in the aluminium matrix strongly affected the measured corrosion characteristics. In addition, the results showed that non-uniformity of type and agglomeration of the particles in the aluminium matrix are related to serious material loss in the tribocorrosion process. The composite with homogeneous distribution of alumina displayed the highest tribocorrosion resistance.
