Abstract
Nickel phosphorus alloy coatings were prepared by electrodeposition route from sulfate electrolyte bath
at various current densities. SEM studies revealed that spherical grains covered the entire surface with uniform
distribution. EDX results showed a linear increase of P content in the developed deposits with current density,
causing an increase in the grains size and a drop in hardness values. XRD studies revealed monocrystalline
orthorhombic alloys at low phosphorus content (10.88 wt. %). Corrosion test results showed that 1 A.dm-2 is the
best applied current density providing the nobler Ecorr (-171.4 mV) and the lower icorr (4.64 μA/cm2).
