Análisis de la corrosión de uniones por soldadura fuerte de compósitos matriz cobre

ABSTRACT This work presents an electrochemical corrosion study in synthetic seawater of the dissimilar joint of TiC/Cu composite by brazing technique. Composites were machined by liquid infiltration without external pressure. This composite were joined with copper using a filler material constituted by an alloy of silver - copper and titanium powder. The composite joined shown a good adhesion forming a dissimilar assembled and coherent. In order to carry out the corrosion studies, two different techniques were used, potentiodynamic polarization curves (PCs) and electrochemical noise (EN). In a...
