  • Effect of Milling on the Hardness and Wear Behaviour of Cast Al6061 Reinforced with Al2O3 Nanoparticles

    Journal of Bio and Tribo Corrosion, 2022
  • Effect of Ball Milling on the Tensile Properties of Aluminum-Based Metal Matrix Nanocomposite Developed by Stir Casting Technique

    SAE International Journal of Materials and Manufacturing, 2021
    <div>Combining ball milling with stir casting in the synthesis of nanocomposites is found effective in increasing the strength and ductility of the nanocomposites. In the first step, the nanoparticles used as reinforcement are generated by milling a mixture of aluminum (Al) and manganese dioxide (MnO<sub>2</sub>) powders. A mixture of Al and MnO<sub>2</sub> powders are mixed in the ratio of 1:2.4 by weight and milled at 300 rpm in a high-energy planetary ball mill for different durations of 120 min, 240 min, and 360 min to generate nano-sized alumina (Al<sub>2</sub>O<sub>3</sub>) particles. It is supposed that the powders have two different roles during milling, firstly, to generate nano-sized Al<sub>2</sub>O<sub>3</sub> by oxidation at the high-energy impact points due to collision between Al and MnO<sub>2</sub> particles, and secondly, to keep nano-sized Al<sub>2</sub>O<sub>3</sub> particles physically separate by the presence of coarser particles. In the second step, 0.5 weight percent (wt%), 1 wt%, 1.5 wt%, and 2 wt% of the generated Al<sub>2</sub>O<sub>3</sub> nanoparticles are reinforced in molten aluminum-magnesium (Al-Mg) alloy matrix via stir casting to synthesize nanocomposites. The effect of milling on the microstructure of the powder mixture before and after milling has been studied with the use of a scanning electron microscope (SEM) and X-ray diffraction analysis (XRD). The microstructure of the cast composites is examined under SEM, and the fractured surface of the tensile specimens is analyzed through SEM fractographs. Ball milling of reinforcement before adding to the melt brings considerable improvement in the integration and uniform dispersion of the milled particle in the Al-Mg alloy matrix melt, which leads to improvement in the strength and ductility of the cast nanocomposites.</div>

    Mechanical alloying has been one of the prominent methods of powder synthesis technique in solid state involving cyclic deformation, cold welding and fracturing of powder particles. Powder particles in this method are subjected to greater mechanical deformation due to the impact of ball–powder-ball and ball-powder-container collisions that occurs during mechanical alloying. Strain hardening and fracture of particles decreases the size of the particles and creates new surfaces. The objective of this Present work is to use ball milling of SiC powder for different duration of 5, 10, 15 and 20 hours by High energy planetary ball milling machine and to evaluate the effect of ball milling on SiC powder. Micro structural Studies using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and EDAX has been investigated.
  • Characterization and study of mechanical and tribological properties on titanium di oxide (TiO2) coated 304L stainless steel
    S. Ghanaraja, Syed Imran Ali, K. S. Ravikumar, P. Likith
    Aip Conference Proceedings, 2018
    In the present investigation Atmospheric Plasma Spraying (APS) method is selected for coating the materials on 304L Stainless Steel as a substrate material, also called as substrate of Thermal Barrier Coating (TBC) system developed in the present work. Commercially available Ni-Cr metal powder is selected for bond coat and TiO2 powder is selected for Top Coat. The thickness of bond coat is taken as 75 µm where as the top coat thickness is varied as 100 µm, 200 µm and 300 µm. In plasma sprayed coating more attention is given to obtain uniform thickness on the given substrate. The various surface texture parameters of each sample is tested, morphology and coating thickness of above TBC system are studied with the help of SEM and X-Ray Diffraction for phase analysis. Micro-hardness of each layer of coating is measured by using Vicker’s diamond indentation and the abrasive wear resistance of each system has been investigated through Pin-on-disc test, at room temperature by using wear and friction tribometer. ...
  • Effect of forging on mechanical properties of rice husk ash-silicon carbide reinforced Al1100 hybrid composites
    S. Ghanaraja, B. L. Gireesha, K. S. Ravikumar, P. Likith
    Aip Conference Proceedings, 2018
    During the past few years, material design has changed prominence to pursue light weight, environment friendliness, low cost, quality, higher service temperature, higher elastic modulus, improved wear resistance and performance. Straight monolithic materials have limitations in achieving the above decisive factors. To overcome these limitations and to convince the ever increasing demand of modern day technology, Attention has been shifted towards Metal Matrix Composites (MMC). Stir casting route is most hopeful for synthesizing discontinuous reinforcement aluminium matrix composites because of its relative simplicity and easy adaptability with all shape casting process used in metal casting industry. Hybridization of metal matrix composites is the introduction of more than one type/kind, size and shape of reinforcement during processing of composites. It is carried out to obtain synergistic properties of different reinforcements and matrix used, which may not be rea1ised in monolithic alloy or in conventional monocomposites. The present study involves synthesis of hybrid composites by addition of the desired amount of Silicon Carbide (SiC) and Rice Husk Ash (RHA) particles in to the molten Al 1100-Mg alloy through stir casting technique fallowed by hot forging of the cast composites. The influence of increasing in the wt% (3, 6, 9, 12 and 15 wt%) of SiC particles addition (3 wt% Rice husk ash kept constant) on evolution of microstructure is studied through XRD and SEM and their impact on the mechanical properties like hardness and tensile strength of the resulting forged hybrid composites has been investigated.During the past few years, material design has changed prominence to pursue light weight, environment friendliness, low cost, quality, higher service temperature, higher elastic modulus, improved wear resistance and performance.
