Studying properties of Al-12WT % Si alloy reinforced with CeO2 nano powders prepared by powder metallurgy

الملخص EN

In this paper, Aluminum – 12wt% Silicon alloys reinforced by cerium oxide (CeO2) nano powder with a different percentage (1, 2, and 3 wt.%) were prepared by powder technology method.

Wear, porosity, apparent density tests were conducted for composite materials and reference alloy.

The results showed that there is a slight change in the density and increases in the porosity of nanocomposite materials compared to reference alloy.

The wear rate decreases with the increase in the proportion of the reinforced particles for the reference alloy as well as the wear rate increases with increased applied load.
