EFFECT OF DEPOSITION TECHNIQUES OF REINFORCEMENT DURING FABRICATION OF AL-BASED SURFACE HYBRID MATRIX METAL MATRIX COMPOSITE

Several deposition methods have been proposed for pre-deposition of reinforcement particle preparation surface metal matrix composite by Friction Stir Process. The method, which will effectively and homogeneously spread the within processed zone, be considered as best possible method.Homogeneous volumetric composites can fabricated conventional casting modified stir methods. process (FSP) used one technique to fabricate composites. In this research article, silicon carbide graphite powder are reinforced materials AA6061 is parent material. FSP a versatile applied fabrication composite. Herein, single channel, multi-channel perforated holes utilized deposition. As per results, blind method reported pre powders. Finally, array improves approx 25% in ultimate tensile strength , 40% micro-hardness appreciable grain refinement observed compared received alloy.
