A team of researchers from the National Institute of Technology Durgapur in India has made a significant breakthrough in nanotechnology by developing an enhanced nanostructured Cu-Ni alloy thin film for marine structures. The research, which utilized molecular dynamics simulations and pulsed electrodeposition, has resulted in a potent nanostructured Cu-Ni alloy thin film with improved mechanical properties and corrosion resistance.

Key Takeaways:

  • The researchers analyzed the effect of variation in Ni percentage on the mechanical properties of polycrystalline nanostructured thin films of Cu-Ni alloy using molecular dynamics simulations and pulsed electrodeposition experiments.
  • Nanoindentation simulations using embedded atom method (EAM) potential were carried out with varying Ni percentage, revealing that the highest values of hardness and Young's modulus were achieved at nanostructured Cu-Ni alloy containing 40 wt.% and 50 wt.% of Ni, respectively.
  • The research team used X-ray diffraction (XRD), high-resolution transmission electron microscopic (HRTEM) studies, scanning electron microscopy (SEM), atomic force microscopy (AFM), and energy-dispersive x-ray spectroscopy (EDX) to analyze the film's structure, grain size, thickness, surface morphology, roughness, and stoichiometry.
  • The nanoindentation test results revealed that hardness and Young's modulus values are in good agreement with simulation results, and the potentiodynamic polarization tests ensured an unaltered corrosion resistance even after the enhancements in mechanical properties.
  • The research concluded that the investigation lays out useful guidelines for designing and developing a potent nanostructured Cu-Ni alloy thin film for advanced applications in marine and naval structures.

Statistics:

  • 40 wt.% and 50 wt.% of Ni in the nanostructured Cu-Ni alloy resulted in the highest values of hardness and Young's modulus, respectively.
  • The grain size of the nanostructured Cu-Ni alloy was found to be near 10 nm.
  • The film thickness was analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM).
  • The surface morphology and roughness were analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM).
  • The stoichiometry of the nanostructured Cu-Ni alloy was analyzed using energy-dispersive x-ray spectroscopy (EDX).
