Electrodeposition is a versatile route to produce new nanocrystalline alloys. Only a few studies concern the corrosion behaviour of these nanocrystalline alloys. In the present paper, the physical-chemical properties of Co-Mo coatings electrodeposited on pure cobalt are investigated by means of field-emission scanning electron microscopy coupled with energy dispersive spectroscopy (FE-SEM/EDS), optical profilometry and microhardness tests. The influence of potential applied during electrodeposition is discussed. The corrosion behaviour of these coatings is then studied in the Ringer's solution at 25 °C. Obtained results are analyzed considering the physical-chemical properties of coatings.
