Development, Characterization And Optimization Of The Physical, Mechanical And Corrosion Behavior Of Fe-Sic-Zro2 Composites

Abstract

The Iron Is One Of The Most Versatile Engineering Materials Having All-Round Applications In Construction, Automobile, Aerospace, Ship, Building Industries Etc. However, Fe Has Lower Corrosion Resistance, Low Strength To Weight Ratio, And High Density. The Aim Involved In Designing Metal Matrix Hybrid Composite Materials Is To Combine The Desirable Attributes Of Metals And Ceramics. Present Work Is Focused On The Study Of Behavior Of Fe/Sic-Zro2 Composites Produced By The Powder Metallurgy. Experiments Have Been Designed Using L9 Taguchi Orthogonal Array To Acquire The Data. Grey Relational Analysis Approach Is Used For Optimization Of Process Parameters In Order To Obtain The Best Values Of Mechanical Properties Like Density, Hardness And Compressive Strength. An Analysis Of Variance Is Employed To Investigate The Influence Of Three Controlling Parameters, Viz., Sic-Zro2 Composition, Compaction Pressure, & Sintering On Sintered Density, Hardness And Corrosion Rate Of The Composites. The Optimal Combination Of The Three Controlling Parameters Has Been Obtained For Minimum Sintered Density, Maximum Hardness And Minimum Corrosion Rate. In 3%Nacl Solution At Room Temperature Where Studied. Furthermore, The Investigation Of Deformation Behavior Through Bulk Deformation I.E., Extrusion Process Has Been Done On The Mechanical, Electrochemical And Microstructural Properties Of The Sintered Sample. The Lower Density Has Been Recorded For Fe-10%Sic-5%Zro2 Specimen. When The Wt% Addition Of Sic And Zro2 Increases, The Hardness And Compression Strength Of The Composites Were Increased. The Highest Hardness (485.4hv) And Compression Strength (310mpa) For The Composite Was Obtained With Fe -10% Sic-10% Zro2 Specimen. The Higher Corrosion Resistance Of The Composites Was Obtained For Fe-10%Sic-10% Zro2 Due To The Addition Of Corrosion Resistance Reinforcement And Well Compacted Of The Sample. The Density And Hardness Of The Sample After Deformation Was Found To Be 5.021 G/Cm3And 544.6hv Respectively, Which Have Shown Remarkable Improvement In Material Properties. Fairly Distributed Of Reinforcement Particle, Good Microstructure And Minimum Porosity Is Shown For Extrudate Specimen. The Results Also Indicate That The Extruded Hybrid Composite Specimens Are Exhibiting Marginally Lower Order Corrosion Rate Compared To Sintered Specimen Of The Similar Specimen From 24.47 To 12.124 (Mpy). This Research Work Is Expected To Help All Industries And Researchers Working In This Area Of Focus.
