Powder Metallurgy Approach To Investigate The Effect Of Olive Tree Ash On Physio-Mechanical, Corrosion And Tribological Properties Of Aluminum Matrix Composite

Abstract

In Recent Years, There Has Been A Significant Increase In The Use Of Aluminum Matrix Composites Especially In, Automotive, Aerospace, Marine And Other Structural Applications. In This Study Aluminum Matrix Composites (Amcs) Were Fabricated By Using Different Weight Percentages Of Olive Tree Stem Ash As A Primary Reinforcement And Additives (Gr And Mg)By Powder Metallurgy Processing Technique. The Fraction Of Olive Tree Stem Ash (Ota)Ranges From 3 To 9 Wt.% At 3 Wt.% Intervals. Whereas, Additives Were 1 Wt.% Mg, And 3 Wt.% Gr According To The Recent Literature Review. In The First, The Production Of Aluminum Matrix Reinforced With 0 Wt.%, 3wt.%, 6wt.% And 9wt.% Of Ota And 3wt.% Gr With 1wt.%Mg With Varying Sintering Temperature Of 4000c, 5000c And 6000c For 2hrs. In The Second, Characterization And Testing Of Ota And Amc Performed. Characterizations Performed Were Thermal Analysis Tga/Dta, Xrd For Phase Analysis, Ftir For Functional Group (Bonding Condition) Identification, Sem For Wear Surface Morphological Examination, And Testing Physio-Mechanical (Hardness And Compressive Strength), Tri biological And Corrosion Test For Fabricated Samples Were Done. Next, Optimization Using Taguchi Multi-Response Grey Relational Analysis L27 Orthogonal Array To Determine The Influence Of Powder Metallurgy (Pm) Process Parameters (Compacting Pressure, Sintering Temperature And Sintering Time) With Varying Composition Of Ota. Finally, Results Of Characterization And Tests Were Discussed. The Xrd Results Of Composites Indicates That All Fabricated Amcs Contain Al As A Major Peak And Minor Peaks Of Reinforcements And Additives At 9wt.% Of Ota. It Also Confirmed Absence Of Intermetallic Peak. Increasing The Wt.% Of Ota Decreased Density Of The Composite And Maximum Hardness And Compressive Strength Obtained At 9wt.% Of Ota Sintered At 6000c For 2hrs. Hardness And Compressive Strength Enhanced That Of Pure Matrix Material 54.2l% And Compression By 52.5% The Resistance Of Wear Loss And Corrosion Increased When Wt.% Ota Increase Up To Certain Limit, Then Decreased. The Confirmation Test Result Of Optimized Sample Revealed That The Optimized One Had Greatest Physio-Mechanical Properties Than Other L27 Samples. Hence This Amc Will Be Suitable For Potential Application In Automotive, Aerospace, Defense, Marine And Structural Application.
