دراسة بعض الخواص الفيزيائية و الميكانيكية لمادة متراكبة ذات أساس من الألمنيوم 6063 مدعم بدقائق الزركونيا و المحضرة بتقانة ميتالورجيا المساحيق

الملخص EN

The aim of this work is studying some physical properties (density , porosity & water absorption) and some mechanical properties (micro hardness Vickers , compression strength & wear resistance) of aluminum 6063 matrix composite material that reinforced by (2.5,5,7.5&10) wt.% of ZrO2 particles.

Powder metallurgy technique is used in samples preparing.

Samples were compacted by using cold uniaxial pressing then followed sintering process at 600 oC under inert gas.Results were showed improving in (wear resistance , compression strength & micro hardness Vickers) and increasing in (density , porosity & water absorption).

Increase micro hardness (44.5 – 101.13), compression strength (36.1998 – 46.7) N/mm2 and decrease wear rate (9.5*exp(-8) – 4.8*exp(-8)) g/cm at time 30 min.

with (0 – 10)% ZrO2.

While increase apparent density (1.388 – 3.15) g/cm3 , apparent porosity (0.96 – 4.61)% and water absorption (0.699 – 2.09)% at (0 – 10)% ZrO2.
