Effects of different impact angles such as 45°and 90°on the erosion-abrasion properties of Al-Mn alloy and its composites reinforced with Al2O3 particulates were studied by rotating erosion-abrasion test, and the failure mechanism were analyzed. The results show that the as-cast Al-Mn alloy is composed of aluminium-manganese solid solution, MnAl6 and Al11Mn4 phase, while the δ-Al2O3 particles are included in the composites besides the aforementioned microstructures. The cumulative mass loss of the Al-Mn alloy and its composites at 45° are both more than those at 90°, however, the loss of the composites are lower than those of the Al-Mn alloy, suggesting that the former possesses more excellent erosion-abrasion resistance properties.
