Deposito electroforético Corrosión Material funcionalmente graduado Superficie hidrofóbica PDMS. The objective of this work is to develop a superhydrophobic and self-healing coating with the ability to protect metal surfaces and extend the useful life of both metal and coating. By means of the electrophoretic deposition technique, titanium dioxide coatings with variable morphology and composition were created. So far two techniques have been used for the manufacture of superhydrophobic coatings: 1) Functionalization of TiO2 nanoparticles (anatase) with polydimethylsiloxane by UV irradiation and 2) Functionalization of electrophoretic deposits with polydimethylsiloxane by UV irradiation. The electrophoretic deposits vary the applied potential and the deposition times, they are observed that they are used, they are eliminated, the uniforms are uniform and homogeneous, they are minimized, they are reduced, they are diminished, they are diminished, they are diminished, they are increased, they are they increase, they increase, they increase, they decrease, they increase, they are deposited first, thus generating a homogeneous arrangement on the surface of the highly rough metal.  All deposits were characterized by FTIR, RAMAN, DLS, UV-vis- Diffuse Reflectance, AFM y FESEM. El objetivo de este trabajo es desarrollar un recubrimiento superhidrofóbico y autoregenerable con la capacidad de proteger superficies de titanio y extender la vida útil tanto del metal como del recubrimiento. Mediante la técnica de deposición electroforética se crearon recubrimientos de dióxido de titanio con morfología y composición variable. Hasta el momento se han empleados dos técnicas para la fabricación de los recubrimientos superhidrofobicos: 1) Funcionalización de nanopartículas de TiO2 (anatasa) con polidimetilsiloxano por irradiación UV y 2) Funcionalización de los depósitos electroforéticos con polidimetilsiloxano por UV. Los depósitos electroforéticos se prepararon variando el potencial aplicado y los tiempos de deposición, se observa que al utilizar potenciales menores los depósitos son más uniformes y homogéneos, se logra observar también que las grietas disminuyen significativamente con la disminución del potencial aplicado debido a que las partículas más pequeñas se depositan primero generando así un arreglo homogéneo en la superficie del metal altamente rugoso. Los depósitos fueron caracterizados por diferentes técnicas: FTIR, RAMAN, DLS, UV-vis de reflectancia difusa, AFM y FESEM.
