Surface morphology of Ni-Co-Si۳N۴ composite coating deposited by pulse current

In the present study, the influence of Si۳N۴ nanoparticles on the surface morphology of the Ni-Co nanocomposite layer were analyzed. For this goal, ۱۵ g/L of Si۳N۴ nanoparticles were embedded into the Ni-Co alloy electrolyte. The coatings were fabricated by a simple electrodeposition method on the St ۳۷ steel. Field-emission microscopy (FESEM) assay was used to determine surface characteristics. Results showed the formation of a dense layer, consisting pyramidal particles.The abstract appears before the keywords. Abstract must be about ۲۰۰ words.
