Anticorrosive evaluation of Sio2-Tio2-Zro2 ceramic trilayers synthesized by the Sol-Gel method
The conformation of trilayers of ceramic coatings of the SiO2-TiO2-ZrO2 system is shown, synthesized by the Sol-gel method, using Si (OC2H5) 4, Ti (OBu) 4 and Zr (OC3H7) 4 as precursors, as EtOH and water, and as a complexing agent 2,4 pentanedione. The ceramic coatings were deposited on AISI / SAE...

| description | The conformation of trilayers of ceramic coatings of the SiO2-TiO2-ZrO2 system is shown, synthesized by the Sol-gel method, using Si (OC2H5) 4, Ti (OBu) 4 and Zr (OC3H7) 4 as precursors, as EtOH and water, and as a complexing agent 2,4 pentanedione. The ceramic coatings were deposited on AISI / SAE 304 stainless steel substrates using the dip-coating technique. The influence of the coatings on the anticorrosive behavior of the substrate in a 3% HCl solution was studied using Electrochemical Impedance Spectroscopy (EIS) techniques and potentiodynamic polarization curves. Additionally, a morphological study was performed using the Atomic Force Microscopy (AFM) technique. The values of the electrochemical parameters were found to change substantially with the concentration of the precursors added to the effects of the film on the substrate. |

Se muestra la conformación de tricapas de recubrimientos cerámicos del sistema SiO2-TiO2-ZrO2, sintetizadas por el método Sol-gel, utilizando como precursores Si(OC2H5)4, Ti(OBu)4 y Zr(OC3H7)4, como solventes EtOH y agua, y como acomplejante 2,4 pentanodiona. Los recubrimientos cerámicos fueron depositados sobre sustratos de acero inoxidable AISI/SAE 304 mediante la técnica de inmersión (dip-coating). Se estudió la influencia de los recubrimientos sobre el comportamiento anticorrosivo del sustrato en una solución de HCl al 3% mediante las técnicas de Espectroscopia de Impedancia Electroquímica (EIS) y curvas potenciodinámicas de polarización. Adicionalmente se realizó un estudio morfológico mediante la técnica de Microscopía de Fuerza Atómica (AFM). Se encontró que los valores de los parámetros electroquímicos cambian sustancialmente con la concentración de los precursores sumada a los efectos de la película sobre el sustrato.
