Abstract EN
High phosphorus Ni-P alloy was deposited on aluminium substrate using electroless deposition route.
Using zincating bath, the surface was activated before deposition.
Deposition time was varied from 15 minutes to 3 hours.
Deposit was characterised using scanning electron microscope with energy dispersive spectroscope, X-ray diffraction, and microhardness tester.
The corrosion resistance was measured using Tafel extrapolation route.
The medium was aqueous 5% HNO3 solution.
The analysis showed that the deposit consisted of nodules of submicron and micron scale.
The predominant phase in the deposit was nickel along with phosphides of nickel.
Compared to substrate material, deposit showed higher hardness.
With increase in deposition time, the deposit showed more nobleness in 5% HNO3 solution and nobleness reached a limiting value in 1 hour deposition time.
