Abstract :

The increasing demand for magnetic materials in the industry has led to the production of Fe-Ni composite magnetic alloys with ceramic particles. In this research, FeNi-WC nanostructure composite was produced using pulse electrodeposition. The effects of pH, current density and the amount of reinforcement on composition and morphology of products were examined, because morphology and chemical composition and structure of samples were studied by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) and X-ray diffraction analysis (XRD). The result showed an increasing pH, increased slightly nickel and decreased iron, and spherical morphology led to change star one. Due to importance of energy saving, effects of variables on the efficiency parameters such as the current efficiency and specific energy consumption were studied. By increasing pH, current efficiency was increased and specific energy consumption was reduced. When the current density increased, current efficiency was reduced and specific energy consumption was increased. In general, more current density (100 mA/cm2) and lower reinforcement (5 g/L) was observed more uniform morphology.
