“…The analysis of TiO2 nanoparticles showed rutile-phase TiO2, with characteristic diffraction peaks of 2θ values at 25°, 41°, 49° and 54° attributed to the (101), (111), (200) and (211) planes, respectively. These results are consistent with the literature [30]. showing no formation of the coating.…”

Introduction− Magnesium alloys have been known for its biocompatible characteristics and tissue restoration properties. On the other hand, TiO2 has been found to decrease the corrosion rates of the magnesium alloys. Objective− In this work, the dip-coating technique was used to coat the magnesium alloy with TiO2 particles in order to evaluate its corrosion resistance. Methodology− The particles were analyzed by Scanning Electron Microscopy (SEM) and visual inspection. Additionally, hydrogen evolution tests were performed to understand the effect of adding TiO2 in corrosion rates of Mg-alloys. Results− The results showed the positive effect of TiO2 in the improvement of the ASTM B107 AZ31B Mg alloys corrosion by an indirect measurement through hydrogen evolution tests. The bare ASTM B107 AZ31B showed a corrosion 29 times faster compared to the coated alloy. The thickness of the coatings obtained using the dip-coating method is thinner than 20 nm. Conclusions− TiO2 particles were aggregated on the surface of the ASTM B107 AZ31B alloy with a controlled speed. SEM images have shown the improvement of the coating when the H2O concentration in the sol increased. Another important parameter is the withdrawal speed during the dip-coat process which was found to be better at a speed of 3mm/min. Hydrogen evolution in the acid solution showed that coated ASTM B107 AZ31B has less hydrogen production during the corrosion test. The dip-coating technique can also be used to coat polypropylene discs entirely. ResumenIntroducción− Las aleaciones de magnesio son conocidas por sus características biocompatibles y propiedades de restauración de tejidos; por otro lado, se ha encontrado que el TiO2 disminuye las velocidades de corrosión de las aleaciones de magnesio. Objetivo− En este trabajo, la técnica de recubrimiento por inmersión se usó para recubrir una aleación de magnesio con partículas de TiO2 y evaluar su comportamiento a corrosión. Metodología− Las partículas se analizaron por microscopía electrónica de barrido (SEM) e inspección visual. Además, se realizaron pruebas de evolución de hidrógeno para comprender el efecto de la adición de TiO2 en la velocidad de corrosión de la aleación de Mg. Resultados− Los resultados mostraron el efecto positivo de TiO2 en la mejora de la corrosión de aleaciones de ASTM B107 AZ31B Mg mediante una medición indirecta a través de pruebas de evolución de hidrógeno. La aleación ASTM B107 AZ31B sin recubrimiento muestra una corrosión 29 veces más rápida en comparación con la aleación recubierta. El espesor obtenido mediante el método de recubrimiento por inmersión es inferior a 20 nm. Conclusiones− Las partículas de TiO2 se agregaron en la superficie de la aleación ASTM B107 AZ31B con una velocidad controlada. Las imágenes SEM mostraron la mejora del recubrimiento cuando aumenta la concentración de H2O en el sol. Otro parámetro importante es la velocidad de extracción durante el proceso de recubrimiento por inmersión, que resultó ser mejor a una velocidad de 3 mm/min. La evolución del hidrógeno en...

a b s t r a c tThe oblique angle configuration has emerged as an invaluable tool for the deposition of nanostructured thin films. This review develops an up to date description of its principles, including the atomistic mechanisms governing film growth and nanostructuration possibilities, as well as a comprehensive description of the applications benefiting from its incorporation in actual devices. In contrast with other reviews on the subject, the electron beam assisted evaporation technique is analyzed along with other methods operating at oblique angles, including, among others, magnetron sputtering and pulsed laser or ion beam-assisted deposition techniques. To account for the existing differences between deposition in vacuum or in the presence of a plasma, mechanistic simulations are critically revised, discussing well-established paradigms such as the tangent or cosine rules, and proposing new models that explain the growth of tilted porous nanostructures. In the second part, we present an extensive description of applications wherein oblique-angle-deposited thin films are of relevance. From there, we proceed by considering the requirements of a large number of functional devices in which these films are currently being utilized (e.g., solar cells, Li batteries, electrochromic glasses, biomaterials, sensors, etc.), and subsequently describe how and why these nanostructured materials meet with these needs.
