Nickel phosphorus (Ni–P) alloy thin films were prepared by electrodeposition on pre-cleaned 
copper substrates using a galvanostatic cathodic electrodeposition method from sulfate 
electrolyte baths at various phosphorous acid concentrations. X-ray diffraction studies reveal that 
with the increase in phosphorus content, the structure of the Ni–P electrodeposited coatings 
transformed from microcrystalline to a mixture of nanocrystalline and amorphous phases, then to 
amorphous phase. Scanning electron microscopic studies reveal spherical shaped grains at low 
phosphorus contents and modules of cauliflower type morphology at higher phosphorus 
concentrations. A systematic study on the relationships between the structure and wear resistance 
of nickel-phosphorus coatings with different phosphorus contents (i. e. 1.5–13.5 wt.% P) and 
under different thermal treatments has been performed. Electrochemical behavior of 
electrodeposited Ni–P alloys was investigated in chloride neutral solutions. Measurements were 
performed by potentiodynamic polarization method. The effects of phosphorus concentration on 
the crystal structure, morphology, hardness, wear resistance and electrochemical behavior of Ni–
P coatings were studied and discussed.
