Abstract- In this study the powder metallurgy technique
was used to prepare the composite materials using the
aluminum powder as the basis metal, with the additions
of the 2, 4 and 6%Wt. of ZrO2-Cu coating and mixing it
manually for 15 minutes at (30-32 oC). Then the mixture
are compacted at pressure 320 MPa and sintering at
640oC in the atmosphere furnace with argon gas
protection.
The physical properties include the green density,
sintering density, porosity, and microstructure were
examined for the prepared samples. X-ray analyzer was
used to identify the phases changes in order to find the
chemical reaction which it can be excepted occurred in
the sintering samples. The result of X-Ray diffraction
shows that there is new phase exist after sintering for all
weight percentage.
