AbstractAs was recently published in the GERPISA newsletter, one of the aims of the research for the new years will be the knowledge of interactions between the organisational company dynamics and the social-economical models of development. If one takes the example of the German exercise in the framework of FUTUR programme, one of the main thematic groups that emerged from the first discussions was preciselly “Mobility: individually atractive and socially sustainable”. Also the IMVP programme at MIT is taking these questions on the “visions for a sustainable future” theme. In the same way the WorTiS Project analysed several scenario topics on the issue of mobility and automotive industry. Those scenario topics are explained and justified in this research paper.

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