In this study the corrosion behaviour of Mo and Mo containing (AISI type 316) and Mo free (AISI type 304) steels were comparatively investigated. It was found that the passivation of Mo starts at - 550 mV (all potentials are reported with respect to SCE) in basic and -1400 mV in acidic media. The transpassive dissolution in both these media was found to take place at 400 mV. The addition of NaCl into the media causes the evolution of oxygen at 1700 mV. The anodic dissolution potential of Mo containing steel 316 was found to be 100 mV more anodic than non-Mo containing 304 steel. It was concluded that the passive layer of Mo consisted of Mo2O3 and MoO2. The metal undergoes to dissolution precipitation mechanism in the transpassive dissolution region.
