Corrosion and Hardness Study of Electroless Ni-P-ZnO Nano-Composite Coatings
Keywords:
Electroless, Ni-P-ZnO, Nano-Coatings, Corrosion, Hardness.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 380C 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.
