    Development of high corrosion resistant (Ni-Fe) alloy coatings from a low concentration bath through multilayer approach
    (SAGE Publications Inc., 2025) Rai, T.Y.; Hegde, A.
    Here, we report the development of high corrosion-resistant (Ni-Fe) alloy coatings from a low-concentration bath through multilayer approach. The corrosion analysis of (Ni-Fe) alloys electrodeposited at different current densities (2.0–5.0 A/dm2) revealed that the coating developed at 2.0 A/dm2, represented as (Ni-Fe)2.0 A/dm2 is highly anticorrosive. The corrosion resistance of monolayer (Ni-Fe)2.0 A/dm2 coating, showing a corrosion rate of 14.71 × 10−2 mm/y was further improved by utilizing multilayer approach. Corrosion study revealed that multilayer coating having 120 layers, represented as (Ni-Fe)2.0/4.0/120 was six times more anticorrosive (with corrosion rate = 2.33 × 10−2 mm/y), compared to its monolayer counterpart. The improved anticorrosion performance of multilayered coatings was explained in the light of advanced instrumental techniques. © The Author(s) 2024.
