“…At three pass, grain refinement, better bonding and even distribution of particles occurs which results in the enhancement of microhardness as compared to two and single pass. Also the increase in microhardness for all specimens follows the same trend which is similar to the results obtained by Yuvaraj et al (2017). …”

Abstract. Aluminium metal matrix composites finds its application in aerospace, automobile, and energy industry owing to their excellent mechanical properties such as low density high strength, light weight, high strength-to-weight ratio and fatigue and corrosion resistances. Further the addition of nano size particles improves mechanical properties of the composites. The present work is focused on the mechanical performances of aluminium SiC nano composites. Instead of making bulk composites, the surface layers on the substrate improve the mechanical properties. For the fabrication of such surface composite layer, the new modification technique, friction stir processing (FSP) is used. FSP technique is used to produce defect-free surface composite with a good bonding and uniform distribution of reinforcement particles within an aluminium matrix. Various process parameters such as rotational speed, transverse feed, and volume fraction of nano SiC, on mechanical properties is investigated. The mechanical properties such as micro hardness and flexural strength were measured using micro hardness tester and universal tensile testing machine respectively.. In addition to that the morphology of the specimen is examined through scanning electron microscope to study them in detail. . IntroductionIn the modern era, a material with high strength is a basic requirement for various engineering applications. In order to satisfy these needs, composite materials have found a wide range of applications in various industrial components and structures because of their improved mechanical properties. Among various types of composites materials available, metal matrix composites plays a vital role in terms of high strength or stiffness, low density, good corrosion as well as fatigue resistance. For further improving the mechanical properties of such composites, the widely practiced method is the incorporation of either micron/Nano-sized inorganic particle in the metal matrix. Most of the properties improvement by incorporation of such nano particles in aluminium metal matrix composites fabricated by friction stir processing route is not fully explored yet.

Among several methods to fabricate Aluminium metal matrix composites, stir-casting technique is used for large-scale production due to its being less expensive. This research is concerned with the fabrication of Aluminium composites with SiC and Jute Ash Particles, for sake of producing a cost-effective composite with enhanced properties. Wear behaviour was studied using pin on disc tribometer and it was found that wear resistance increases with-addition of reinforcement particles. Fabricated composite samples showed almost 4 times better wear resistance compared to base material. Matrix metal reinforced with SiC showed the best wear resistance of all fabricated samples. Coefficient of friction significantly decreased with the presence of reinforcement due to formation of mechanical mixed layer. Tensile Strength was escalated with the introduction of reinforcement as load is transferred to strongly bonded reinforcement particles. Microhardness was enhanced with the introduction of reinforcement and Sample 2 with SiC as reinforcement showed the best microhardness. Microstructure and fractography of the base metal and fabricated composites was analyzed by Scanning Electron Microscope (SEM).

In many applications, surface properties of materials or components are more important than the entire volume material properties. The hardness, wear and corrosion resistance of material mainly depends on the surface properties. Improved surface properties also increased the life span of components. The friction stir process is a novel solid-state processing technique that is widely used for welding difficult-to-weld materials. In this paper, the applications of the friction stir process in surface modifications and fabrication of aluminum matrix surface composites were discussed. The effects of friction stir process parameters, tool design, reinforcement and reinforcement techniques on the surface properties were also reported.
