    Aluminum nitride (AlN) reinforced electrodeposited Ni-B nanocomposite coatings by Radwan, A. Bahgat

    Published 2020
    “…The potentiodynamic analysis exhibited that the protection efficiency (PE%) of Ni–B coating is ~20%, which increased to ~53% and ~73% by addition of AlN nanoparticles of 0.6 and 1.2 g L−1, respectively. The corrosion resistance could be credited to the presence of inactive and insulating AlN nanoparticles that filled the existing defects in Ni–B matrix and subsequently decreased the active area exposed to the corrosive electrolyte (3.5 wt.% NaCl).…”
