Fabrication and characterization of amorphous/nanocrystalline Fe-Ni-P electrodeposited coatings

Fabrication and characterization of amorphous/nanocrystalline Fe-Ni-P coatings by means of electrodeposition process was the goal of this study. For this regards, plating was carried out at four different current densities in the range of 1030A/dm2. The produced coatings were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results exhibited that the structure of electrodeposited coating at different current densities is a combination of amorphous and nanocrystalline phases. By increasing the current density, the percentage of amorphous phase increases and the crystallite size of crystalline phase decreases. It was observed that, Fe, Ni and P content of coatings at different coating conditions are in the ranges of 63-67 Wt %, 16-17 Wt% and 15-19 Wt%, respectively. The surface morphology of produced coatings was smooth and changed with current density
