Ejemplo 2
Se usó Zn puro como metal de sustrato. Se usaron las mismas nanopartículas de ceria y MAP puras que las usadas en el ejemplo 1.
Las superficies de muestra de Zn se lijaron en húmedo sucesivamente con papel de lija de 500, 800, 1200 granos, tras limpiar, se dejaron las muestras durante la noche en un recipiente cerrado. Se realizó la deposición de la película de material compuesto al día siguiente.
Se preparó disolución de MAP nueva 2 min antes de la inmersión. Para la deposición de la película, la disolución de MAP contiene MAP 0,1 mg/mL, ácido cítrico al 1% y NaCl 50 mM, y el pH era de 6. La disolución de ceria contiene 500 ppm de nanopartículas de ceria dispersadas en agua y NaCl 50 mM. El procedimiento de deposición de la película fue el mismo que el habitual: 1 hora de inmersión en la disolución de MAP y 40 min en la disolución de ceria, sin aclarar con agua entremedias. Se realizó la deposición de la película alternando inmersión en la disolución de MAP y disolución de ceria 4 veces.
Se indicó que, al inicio de la segunda inmersión en la disolución de MAP, se observó algo de producto de reacción como capa grisácea que flotaba en la superficie de la disolución de MAP. El producto de flotación empezó a aparecer en la disolución de MAP tras la primera deposición de ceria, y se observó en todas las etapas adicionales para la deposición de la película en la disolución de MAP.
Se expusieron las muestras de Zn con la película de material compuesto de MAP y nanopartículas de ceria depositada a la disolución de NaCl 0,1 M con H3PO4 0,2 M a pH 4,6, se registró el potencial de circuito abierto (OCP) de manera continua durante 15 minutos, y entonces se realizó EIS tras 1 hora, 1, 3 y 7 días de exposición, como para las muestras de acero al carbono (ejemplo 1).
Los resultados de 3 mediciones paralelas muestran una buena reproducibilidad, por lo que únicamente se presentan los resultados de un conjunto de muestras en este informe.
La figura 8 muestra el OCP frente al tiempo para la muestra de Zn con la película de material compuesto de MAP y ceria en el inicio, tras 1 hora, 1, 3 y 7 días de exposición. En el inicio, el OCP de la muestra estaba a aproximadamente -1,1 V frente a Ag/AgCl, lo cual es similar a Zn sin ninguna película de superficie. Esto indica que la película de material compuesto de MAP y ceria es permeable al electrolito. El OCP aumentó ligeramente tras 1 día, indicando que se había producido algún cambio en la película de superficie. Sigue con que el OCP aumentó significativamente con el tiempo, alcanzado aproximadamente -0,7 V tras 3 días y -0,6 V tras 7 días. Está claro que, durante la exposición, tienen lugar algunas interacciones en las películas de material compuesto y/o entre la película y productos de corrosión de Zn, que conducen a un ennoblecimiento pronunciado de la superficie de Zn. Por consiguiente, esto dio como resultado una protección potenciada frente a la corrosión de Zn en la disolución, tal como se confirmó mediante las mediciones de EIS.
La figura 9 muestra diagramas de Bode típicos de los espectros de EIS obtenidos para la muestra de Zn con la película de material compuesto de MAP y ceria tras 1 hora, 1, 3 y 7 días de exposición. Como puede observarse a partir de los espectro de EIS, con una exposición prolongada, la muestra presenta cada vez más comportamiento capacitivo, y la impedancia en el extremo de frecuencia baja (una media de resistencia a la corrosión) aumentó aproximadamente dos órdenes de magnitud. Los resultados sugieren una gran potenciación en la resistencia a la corrosión de la muestra, lo que implica que la capa de superficie (película de material compuesto y productos de corrosión) se vuelve más protectora con la exposición.
Debe mencionarse que Zn es un metal activo que habitualmente se corroerá rápidamente en disoluciones ácidas o disoluciones de NaCl porque no se formarán productos de corrosión estables sobre la superficie, y el OCP permanece en el nivel bajo debido a la reacción de corrosión electroquímica dominante de Zn. Basándose en los resultados anteriores, puede concluirse que la película de material compuesto de MAP y ceria tiene un mecanismo de protección para el sustrato de zinc en la disolución.
Las figuras (figuras 10a-10d) muestran una comparación entre los resultados de EIS de la muestra de Zn con la película de material compuesto de MAP y ceria y los de la muestra de control sin ninguna película. Aparentemente la resistencia a la corrosión de la muestra de control también aumentó con la exposición en esta disolución. Los inventores especulan que esto puede ser un resultado de la interacción entre Zn y ácido fosfórico presente en la disolución, similar a un tratamiento con fosfato.
