摘要：

The aim of this paper was to determine the effects of different immersion times on electrochemical behaviour of pure molybdenum in NaCl solution (0.1 M). Immersion tests were conducted in different time span. Scanning electron microscope (SEM) indicated that there was not any pitting formation of corrosion products after immersion. The most significant consideration which obtained from Molybdenum EDS maps before and after immersion in solution of 0.1 M NaCl shows increases in combination of oxygen. Pure molybdenum is indicated to have a passive behavior in the given solution by using potentiodynamic polarization (PDP) plots. In addition, electrochemical impedance spectroscopy (EIS) reveals that molybdenum total resistance increases considerably while rising the immersion time.
