Abstract EN
ron-based composites have found a lot of industrial applications such as bearings, camshafts, connecting rods, pulleys, various valves, oil pump gears and many otherapplications in the automotive and other industries due to their low cost, availability, and high strength.
The present study aims to prepare Fe-10 vol.
% Cu- (0 – 5) wt.
% nano Y2O3 composites by powder metallurgy technique and studyingtheir physical and mechanical properties.
The powders were mixed into ball millfor 30 minutes, followed by room temperature uniaxial compaction at 700 MPa for3 minutes.
The green specimens were sintered at 1000 oC for 1 hour.
The results ofthe present study showed that nano yttrium oxide has significant effects on bothphysical and mechanical properties of Fe-10% Cu composite.
The bulk density wasincreased by 0.92% and the true porosity was decreased by 6.4% on increasing thenano oxide content from 0% to 3% respectively.
Vickers microhardness wasincreased by 5.9% on increasing Y2O3 up to 1% followed by gradual decrease onfurther increase above 1% .
Wear rate was decreased by 21% on increasing the nanooxide content from 0% to 3% .
On the other hand, the compressive strength wasdecreased by 47% on increasing Y2O3 up to 5% .
