Titanium is one of the materials that presents corrosion resistance to acid,<br />

saline and most of fuels; it also has an important mechanical resistance, thanks<br />

to these properties are mainly use in the aeronautical, medical and chemistry<br />

industry. Different authors have been interested in studying this material mainly<br />

in presence of chloride ions solutions and saline synthetic solutions in order to<br />

avoid corrosion of said material. At present, few authors have been interested<br />

in the study of corrosion with purpose of using it as a method of obtaining<br />

electrochemically active surfaces, which can be used as substrates for the<br />

selective deposition of metal ions. In the present work, the results of the study<br />

of the energetic conditions for the controlled production of titanium pits, in<br />

corrosive medium rich in chlorides, in order to elaborate electrodes of modified<br />

surfaces that can be use in specific technological developments. A flat<br />

electrochemical cell of three electrodes was assembled using titanium samples<br />

as working electrode, saturated calomel (SCE) as reference electrode and a<br />

graphite bar as auxiliary electrode; then, the electrochemical cell was coupled to<br />

a potentiostat-galvanostat GAMRY to perform the electrochemical techniques of<br />

Potentiodynamic Polarization and Electrochemical Impedance Spectroscopy<br />

were used for pitting generation. The obtained surface was characterized with<br />

Scanning Electron Microscopy.<br />
