aiming at complementing the current knowledge about the wear behaviour of centrifugally-cast&lt;br /&gt;
FGM Al/SiCp composites, through concurrent corrosion processes. Precursor MMC’s were&lt;br /&gt;
prepared by rheocasting, using 118.8 μm SiC particles and an Al-10Si–2.2 Mg alloy. Those MMC’s&lt;br /&gt;
were then molten and centrifugally cast in order to produce cylindrical FGMMC’s. Discs machined&lt;br /&gt;
from the top surface of each sample were tested against nodular cast iron pins, using an inverted&lt;br /&gt;
configuration pin-on-disc tribometer. Sliding tests took place at room temperature, over a 50000 m&lt;br /&gt;
sliding distance, with a sliding speed of 0.3 m s-1, under a 5 N normal load; both dry-sliding and&lt;br /&gt;
water-lubricated tests were performed. In order to elucidate the mechanisms involved, the wear&lt;br /&gt;
coefficients were calculated for each condition, and the samples were subjected to morphological&lt;br /&gt;
characterization via SEM/EDS. Concurrently, in the case of the water-lubrication tests, the&lt;br /&gt;
corrosion potential of the tribological pair was monitored. The results obtained show an increase in&lt;br /&gt;
material loss for the water-lubricated cases, although variations are registered depending on&lt;br /&gt;
reinforcing particle volume fraction. At the same time, the open circuit potential response of the&lt;br /&gt;
tribological pair may be correlated with the events of formation/destruction of the tribolayers.&lt;/p&gt;
