This work shows the electrochemical study of dissimilar joint of inconel 600 to TiC/Ni immersed in synthetic seawater. The composite-inconel 600 assemblies were brazed with BNi3 alloy by brazing technique. The corrosion rate (CR) was evaluated from the technique of electrochemical noise (EN). In addition, the corrosion potential measures as a function of the time were carried out to get the stabilization time of the anodic and cathodic reactions. Electrochemical measurements were carried out under static conditions, ambient temperature and atmospheric pressure, the electrochemical results show that the susceptibility of localized corrosion of composite sample was higher than the joints. The corrosion process is of mixed type, that us to say a process of transfer of load influenced by a mechanism of mass. Analysis by scanning electron microscopy (SEM) revealed that mechanism corrosion was cells differential aeration (difference of concentration of oxygen).
