    Microstructure evolution in Al 6061 coating deposited on Al 2024 substrate by friction surfacing
    (Elsevier Ltd, 2022) Sudhish, R.; Udaya Bhat, K.
    In the present investigation, the microstructure evolution in Al 6061 coating deposited by friction surfacing on Al 2024 was studied in detail. The age hardening behaviour of the developed coating was also analysed. The Al 6061 tool material was solutionized prior to the coating process. The microstructural analysis revealed that, an ultra-fine grain microstructure could be achieved in coating by the coating process wherein the Al 2024 substrate has marginal modification in microstructure. Continuous dynamic recrystallization is identified as the mechanism of ultra-fine grain formation. Also, it was found that the process induced thermo-mechanical effect causing an increment in ageing kinetics. The enhanced ageing kinetics and formation of ultra- fine grains collectively improved the peak aged hardness of the friction surface coating, made using Al 6061. © 2022 Elsevier Ltd

    Optimization of Process Parameters for the Friction Surface Coating of Al 6061 on Al 2024 for Wear Applications
    (American Institute of Physics Inc., 2022) Sudhish, R.; Udaya Bhat, K.
    The present work investigates the role of process parameters on the wear property of friction surfaced Al 6061 coating on Al 2024 substrate material. For this study, after many optimization experiments, four samples with different friction surface forces were prepared. Several mechanical and metallographic characterizations were conducted on the samples that including hardness analysis, metallographic analysis using optical microscopy, scanning electron microscopy and transmission electron microscopy, elemental analysis using energy dispersive spectroscopy, and phase analysis using X-ray diffraction spectroscopy technique. From the results, it is found that the hardness, as well as wear property, has been improved with the increase of friction surfacing force. © 2022 American Institute of Physics Inc..
