Abstract

In current investigation, Ni-P-ZnO nano-composite covering has been urbanized on exterior of MS substrate by
EL procedure. The next stage ZnO nano-particles were synthesized, to add in into EL Ni-P medium. 5 gpl of
ZnO nano-particles were supplementary to Ni-P acidic unit for co-deposition. The heat management of as-
prepared Ni-P/Ni-P-ZnO EL outside layer was conceded out at 380C in Argon for 1h. These coatings were
analysed for surface morphology, elemental composition and phase analysis by FESEM, EDAX, and XRD
analysis. Corrosion resistance quality of depositions was conceded out in 5 % NaCl solution by long term
immersion experiment. Hardness is measured by micro-hardness tester. A consistent allocation of ZnO nano-
particles in EL Ni-P medium is long-established by FESEM/EDAX results. Corrosion and hardness
examinations put forward that EL Ni-P-ZnO coatings illustrate superior performance as judge to simple Ni-P
depositions.
