    Nickel coating on high strength low alloy steel by pulse current deposition (2015)
    Institute of Physics (IOP)
    Details
    Publication Date: 2015-02-20
    Description: Nickel is a silvery-white metal mostly used to enhance the value, utility, and lifespan of industrial equipment and components by protecting them from corrosion. Nickel is commonly used in the chemical and food processing industries to prevent iron from contamination. Since the properties of nickel can be controlled and varied over broad ranges, nickel plating finds numerous applications in industries. In the present investigation, pulse current electro-deposition technique has been used to deposit nickel on a high strength low alloy (HSLA) steel substrate.Coating of nickel is confirmed by X-ray diffraction (XRD) and EDAX analysis. Optical microscopy and SEM is used to assess the coating characteristics. Electrochemical polarization study has been carried out to study the corrosion behaviour of nickel coating and the polarisation curves have revealed that current density used during pulse electro-deposition plays a vital role on characteristics of nickel coating.

    Intelligent Avionics System Onboard An Aircraft Enhancing Communication (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-06-28
    Description: Communications connect the flight deck to the ground and the flight deck to the passengers. On-board communications are provided by public-address systems and aircraft intercoms. Inefficient communication may lead to a catastrophe risking lives and resources. SKYVOIX, an intelligent system on board that enhances safety and improves the communication of the aircraft by reducing human error and increasing the awareness. The system is intended to be centralized and installed in addition to the current systems. With high air traffic and busy airspace, the transmissions are often misheard causing communication failure which is undesirable. A backup for enabling communication with the ground in emergencies is required which ensures active transmissions and is intelligent enough to handle the gravity of situation. The passengers who are often unaware about the routine and emergency protocols, busy with their electronics, listening to music cutting them off with the environment shall be...

    Free vibration analysis of functionally graded sandwich flat panel (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-07-13
    Description: In this paper, the free vibration behavior of functionally graded ceramic-metal sandwich flat panels is investigated. The sandwich panels are considered to be composed of metal rich face layers with varying composition and a homogenous isotropic ceramic core layer. The kinematics of the panels is modeled using ANSYS commercial package. The convergence and the validity of the present model have been established by comparing the present results with the benchmark results available in published literature. Subsequently, the influence of power index, symmetry type and the support conditions on the non-dimensional fundamental frequency is investigated. The fundamental frequency is found to decrease with increasing power index value and increase with number of constraints at the support. The stiffness of the panels is affected by core thickness and the panels with higher core-to-face thickness ratio are observed to have lower fundamental frequency.

    Analysis of vibro-acoustic response of un-baffled laminated composite conical shell panel with varying thickness (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-07-15
    Description: This article presents the vibro-acoustic modeling and analysis of un-baffled laminated composite conical shell panels with varying thickness subjected to harmonic point load. The variation of thickness is considered to be unidirectional. A simulation model for the vibrating panel is developed using the commercial finite element package (ABAQUS). The natural frequencies are computed and compared with available published values for validation purpose. Then, the modal values are exported to LMS Virtual.Lab environment where an indirect boundary element approach has been adopted to extract the coupled vibro-acoustic responses. The sound power radiated by the vibrating structure computed using the present scheme is compared with the results available in the published literature. A comprehensive study has been performed to highlight the effect of thickness variation, excitation location, lamination scheme and support conditions on the acoustic radiation responses of the laminated coni...

    Improvisation of mechanical and electrical properties of Cu by reinforcing MWCNT using modified electro-co-deposition process (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-05-02
    Description: Multi-walled Carbon nanotubes–copper (MWCNT/Cu) composite powders with variable MWCNT content were synthesized by modified electro-co-deposition method. The electro-co-deposited MWCNT/Cu powders were consolidated by conventional compaction and sintering process. The consolidated products were then hot rolled and cold drawn to fine wires. The MWCNT/Cu composite wire samples were characterized for electrical and mechanical properties. We have been able to achieve an increase of around 8% in electrical conductivity of the form wires repeatedly. It has been observed that there was gradual improvement in the properties with reinforcement of MWCNT in the copper matrix. The betterment of electrical property has been achieved with simultaneous improvement in mechanical properties of the wire. The yield strength of MWCNT/Cu composite wire was found to be four times and the tensile strength two times greater than that of pure copper. The improved properties are attributed to the proper di...

    Comparison of Piezo-material based Energy Transduction Systems for Artificial Nanoswimmer (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-05-02
    Description: The energy harnessing is a process of obtaining energy from the surrounding environment and converting into electrical energy. In the last two decades, there has been a plenteous study in energy harnessing. Now a day, energy harnessing using piezoelectric materials has drawn attention of researchers due to low cost, flexibility and light weight. The benefits of piezoelectric material can be utilized by designing a self-powered device for artificial nanoswimmer. Some of the ceramics which displays the piezoelectric effect are lead-zirconate-titanate (PZT), lead-titanate (PbTiO 2 ), lead-zirconate (PbZrO 3 ) and Barium Titanate (BaTiO 3 ). PZT is most extensively used piezoelectric material in the field of energy harnessing but it is brittle in nature. Lead based piezoelectric materials are toxic in nature and may not suitable for in-vivo biomedical applications. To eradicate this problem, researchers are interested in synthesizing lead free piezoelectri...
