Abstract

Binary Ni-Mo alloys were electrodeposited in citrate electrolytic solution at a pH of 9.5. EDS analysis determined the deposit composition and increase in the % wt of Mo with increased applied current density (c.d.). XRD analysis reveals deposits exhibit single Ni-Mo solid phase. SEM micrograph shows that the morphology is clearly altered when the Mo concentration increases. Corrosion behavior of nanocrystalline Ni-Mo alloys was carried out potentiodynamically and electrochemical impedance spectroscopy in 0.5 M H2SO4. The corrosion resistance of the coatings was explained based on the structural interpretation of Ni-Mo alloys. The highest corrosion resistance accompanied by electrodeposits containing least wt% of Mo.
