| Abstract | |
Recently it was shown that the Al-Cu-Fe-Cr system can form a microstructure consisting mainly of quasicrystalline and alpha-Al phases by arc-melting and subsequent annealing of an appropriate composition. In the present work we demonstrate that it is possible to fabricate a large volume of this composite directly from the liquid phase by spray forming an Al85Cu6Fe3Cr6 (%at) alloy. The overspray powder and an arc-melted sample were also analyzed. Tribological properties of the Al-based composite reinforced with quasicrystals was evaluated by pin-on-disk tests, which demonstrated to be superior than an Al-Si alloy, A380, used in this work as a comparison material.
