The Effect of Adding ZrO 2 -Cu coating on The Physical Properties of Aluminum Matrix Composites Dr. ABD AL-ALKAREEM FLAEH Dr.NUHA HADI JASIM University of Basrah University of Basrah College of Engineering College of Engineering Mechanical Engineering Department Material Engineering Department 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 ZrO 2 - Cu coating and mixing it manually for 15 minutes at (30-32 o C). Then the mixture are compacted at pressure 320 MPa and sintering at 640 o C 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. رΩ اΔضافر اϴ تأثΔ سΩاϮϤ الϲ فΔϴائϳΰϴاص الفϮΨ الϰϠ عα بالنحاϲϠطϤ الϡϮϴنϮركΰ الΪϴكسϭ ا ΔΒركϤ الϡϮϴنϤالن اϣ αسا اΕاΫ Ϋأستا اΪساعϤ الرϮكتΪ ال حسنحϴϠ فϢϳ الكرΪΒ عαرΪϤ الرϮكتΪ الϱΩ هاϰϬ نϢ جاس Δعϣ جاΓصرΒ ال/ ΔϴϠ كΔسΪنϬ ال/ Ϣ قسΔسΪنϬ الΔϴكϴكانϴϤ الΔعϣ جاΓصرΒ ال/ ΔϴϠ كΔسΪنϬ ال/ Ϣ قسΔسΪ هنΩاϮϤ ال ΔاصΨ ال رϮ كطϡϮيϨϤϟا΍ ϕϮحδϣ ϡ΍ΪΨΘγك بأϟΫϭ ΔΒكήϤϟ΍ Ω΍ϮϤϟ΍ ήحضيΘϟ ϖحيΎδϤϟ΍ ΎرجيϮϟΎΘيϣ ΔيϨϘΗ ΖϣΪΨΘγ΍ ΔيϟΎحϟ΍ Δγ΍رΪϟ΍ في ΔفΎض΍ عϣ αΎγ΍ ) ΔϔϠΘΨϣ Δيϧίϭ بδϨ بαΎحϨϟΎي بϠطϤϟ΍ ϡϮيϧϮركΰϟ΍ Ϊيδكϭ΍ 2 ، 4 ، 6 ΓΪϤϟ ΎيϭΪط يϠΨϟ΍ ϢΗ ، حيثΔيϧίϭ ΔΒδϧ(% 51 ضغطΖحΗ βΒϜϟ΍ Ϣ ثϦϣϭ Δفήغϟ΍ Γر΍ή حΔرجΩ فيΔϘيϗΩ 323 ΪيΒϠΘϟ΍ Γر΍ή حΔرجΩϭ ϝΎϜγΎبΎϜيϣ 643 ΔيϮΌϣ ΔرجΩ ϥήϔϟ΍ Ϯ في جϥϮآرك΍ ίΎ غϡ΍ΪΨΘγ بأ. ι΍ϮΨϟ΍ κ فحϢΗ ΔيϣΎδϤϟ΍ ,(ΪيΒϠΘϟ΍ ،ء΍ήضΨϟ΍) ΕΎفΎثϜϟ΍ ΖϨϤضΗ يΘϟ΍ϭ ΔئيΎيΰيϔϟ΍ ر΍Ϯاط΍ ήغيΗ κيΨθΘϟ .ΓήحضϤϟ΍ ΕΎϨعيϠϟ يήϬجϤϟ΍ كيبήΘϟ΍ϭ ϢΗ Θγ΍ ΍ΪΨ ϞعΎϔΘϟ΍ ضيحϮΘϟ ΔيϨيδϟ΍ Δاشع΍ ΩϮ حيϞيϠحΗ ϡ عϗϮΘϤϟ΍ ئيΎيϤيϜϟ΍ .ΓΪΒϠϤϟ΍ ΕΎϨعيϟ΍ فيΔثϭΪ ح
