Description |
Ni-Mo composite coatings were obtained on pretreated copper substrates by electrolytic deposition in which molybdenum powders were held in suspension. The electrodeposition process was carried out at a current density rang of 100-300 mA/cm2 and a temperature of 303 K during 90 minutes. The surface morphology of the coatings was examined by scanning microscopy (SEM). X-ray diffraction method was used to determine the phase composition of the layers. The coatings deposited were uniform and adherent to the substrates. It was revealed that composite coatings are characterized by a fissured and porous surface in comparison with pure nickel coating deposited. X-ray examination of the Ni-Mo layers indicated that they have a three phases (MoNi4, Mo1.24Ni0.76 and Ni3Mo) of crystallites of nickel and molybdenum.
