Influence of Dissolved Oxygen on the Corrosion Behaviour in Ringer's Solution and Artificial Saliva of Co-Mo Nano-Crystalline Coatings Electrodeposited on Co and 316L Substrates

The influence on the corrosion behaviour of Co-Mo nano-crystalline coatings of dissolved oxygen is studied in the Ringer’s solution and artificial saliva at 25°C. This was done by means of potentiodynamic tests and surface observations. It was shown that dissolved oxygen has no influence on passivity, oxidation of the coating and selective dissolution of cobalt. By contrast, dissolved oxygen affects corrosion. General corrosion was observed in the Ringer’s solution whereas pitting corrosion was found in artificial saliva.
