Effect of Si۳N۴ nanoparticles on microhardness and corrosion resistance of Ni-Co electrodeposits

In the present study, the effect of Si۳N۴ nanoparticles on the microhardness, and corrosion resistance of the Ni-Co nanocomposite layer were analyzed. For this goal, ۵ g/L of Si۳N۴ nanoparticles were incorporated into the Ni-Co alloy electrolyte. Vickers microhardness and electrochemical impedance spectroscopy (EIS) assays were used to determine the microhardness and corrosion resistance of the coatings, respectively. Results showed that the added nanoparticles increased the microhardness and charge-transfer resistance of the Ni-Co coatings by ≈۱۰۰ HV and ≈۴۰ kΩ cm۲, respectively.

Keywords:

Si۳N۴ nanoparticles , microhardness , corrosion resistance , Ni-Co , coating.
