Corrosion and Hardness Study of Electroless Ni-P-ZnO Nano-Composite Coatings
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 mediumis 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.
