The Effects of Deposition Time on Phase and Structure of FeCoNi Films
Keywords:FeCoNi, phase, structure, current efficiency, deposition rate
This study aims to determine the effects of deposition time on the phase and structure of FeCoNi. FeCoNi was prepared by electrodeposition method at room temperature. X-ray diffraction measurement shows the formation of a single phase of FeCoNi at 5 and 10 minutes of deposition, while at 20, 35, and 50 minutes, a new phase was formed, namely CoNi. The obtained FeCoNi and CoNi show a crystal plane at 2θ = 44.05° (111); 51.33° (002); and 75.59° (022) in all different deposition times, indicating the face centered cubic crystal structure. The effect of deposition time on the chemicals composition shows an anomalous co-deposition because Fe has a larger ratio than Co and Ni. The deposition rate and the value of current efficiency were found to be optimum at FeCoNi synthesized for 20 minutes, namely 0.00214 mg/cm2s and 97.00%.
