Anti-corrosive and anti-microbial properties of nanocrystalline Ni-Ag coatings

- Electrodeposition yielded phase-segregated, nanocrystalline Ni-Ag coatings.
- Ni-Ag alloys exhibited smaller Ni crystals compared to pure Ni.
- Ultra fine Ni grains of size 12-14 nm favoured Ni-Ag solid solution.
- Nanocrystalline Ag resisted bio-fouling by Sulphate Reducing bacteria.
- Ni-Ag outperformed pure Ni in corrosion and bio-corrosion tests.
