The Ni–P/DNP nanocomposite coatings were sono-deposited on mild steel through a nickel electroless
bath containing ultrasonically dispersed diamond nanoparticles (DNP). The surface morphology, composition
and structural properties of coatings were studied by scanning electron microscopy, energy-dispersive
X-ray spectroscopy, and X-ray diffraction, respectively. The effect of the various contents of DNP on
corrosion behaviour of prepared coatings was evaluated in NaCl solution by different electrochemical
methods. The results indicated that the incorporation of DNP significantly improves corrosion resistance
of Ni–P coatings. Accordingly, good correlation exists between various experimental results that obtained
from different techniques.
