Characterization And Structure Of Ni-AIn Nanocomposite Layers Fabricated By Pulse ESectro-Deposition 19

摘要

The pulse electro-deposition (PED) has been successfully applied for fabricating nanocomposite layers on the surface of steel substrates. The Ni-AIN nanocomposite layers were fabricated by mixing a given amount of A1N particles in electrolyte ultrasonically. The composition and surface morphology of the layers were investigated by means of XRD and SEM. The results showed that the Ni-AIN nanocomposite layers consisting of nickel grains (-68.27 nm) and A1N nanoparticles (~38.46 nm) had been obtained on the surface of steel substrates by PED. The Ni-AIN layer exhibited a compact surface morphology in micro-regions, and the grain sizes in the Ni layer were greater than that in the Ni-AIN nanocomposite layer.
