Abstract
⺠In this work is presented the microstructure and tribocorrosion behaviour of Al/Al3Ti and Al/Al3Zr functionally graded materials (FGMs), fabricated by the centrifugal method. ⺠Higher applied centrifugal force increases both the intermetallic particles volume fraction as well as their orientation in the outer regions of the FGMs. ⺠The materials produced with higher centrifugal force demonstrated better tribocorrosion. Additionally, it was observed that the tribocorrosion mechanisms of Al/Al3Ti and Al/Al3Zr FGM samples are different, and dependent on the mechanical properties of the reinforcing platelets. The existence of a synergism between the wear and the corrosion is apparent, as higher mechanical wear results in higher relative amount of corrosion.
