Description- Improved surface characteristics while retaining the bulk properties is the unique characteristic of the surface composites. Friction stir processing (FSP) is a novel and green process for fabrication of surface composites. In this work, synthesis of AA 6063/Sic surface composites via FSP is reported. A single pass FSP was carried out on AA 6063-T6 plates with SiC reinforcement particles using constant tool rotational speed of 1120 rpm and varying traverse speeds of 30 mm/min, 40 mm/min and 50 mm/min with tool tilt angle of 2. Optical microscopy was used to study the effect of traverse speed on the microstructure of the fabricated surface composites. Results show that SiC particles were uniformly distributed in the metal matrix. Optimal homogeneity in distribution was obtained corresponding to the traverse speed of 40 mm/min. It was further noted that there was no interfacial reaction found between the aluminium matrix and SiC particles.Virtual modelling and simulation of functionally graded material component using FDM technique

Description-Functionally graded materials (FGM) which are also called tailor made materials, are composites with continuously varying mechanical properties. The limitations on the component materials available for specific RP processes calls for the development of tailor made material properties in the available material options. This paper proposes a technique to develop and fabricate FGM using Fused Deposition Modelling (FDM) technique. An attempt is made to relate the FDM process parameters with the material properties for the given ABS material. These relations are used to assign tailor made properties to the component in various regions. By actual CAD modeling and analysis using ANSYS 14, it is established that the deformation due to given load is considerably reduced for the component made by assigning unique set of parameters in a customized fashion.
