Materiales catalíticos para aplicaciones en celdas de combustible de hidrógeno/oxígeno como aporte a la transición hacia fuentes de energía renovables
(Universidad Nacional de Misiones. Instituto de Materiales de Misiones, 2020-09-20)
La producción de energía mediante combustión térmica convencional de fuentes fósiles presenta serias desventajas, ya que como método indirecto e ineficiente implica una etapa intermedia de conversión de calor en trabajo ...
Corrosion of nonferrous metals and their alloys
(Hindawi, 2018-05-31)
Corrosion is the result of the interaction of a material (metal) with its environment.
Thecorrosion process depends on the properties of both metal (and alloy) and surrounding environment. Usually, the more important ...
Aproximación del comportamiento de ladrillos cerámicos huecos mediante métodos numéricos
(Asociación Argentina de Mecánica Computacional, 2017-11-10)
En la provincia de Misiones, Argentina, se destaca el uso frecuente de mampuestos conocidos como Ladrillos Cerámicos Huecos (LCH), los cuales son de fabricación industrial, moldeados con máquinas extrusoras, cocidos en ...
Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation : photocatalytic reduction of Cr(VI)
(Elsevier, 2017-04-15)
Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200–3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ...
Electrochemical analysis of the ASTM F75 alloy at different pH values and temperatures
(Wiley, 2017-02-27)
The electrochemical behavior of ASTM F75 alloy was analyzed in a sodium chloride solution at pH values of 5, 7, and 9 and temperatures of 37 and 42 °C. The tests were performed in samples corresponding to two different ...
Synthesis and morphological characterization of nanoporous aluminum oxide films by using a single anodization step
(MDPI AG, 2019-02-13)
Nanoporous anodic aluminum oxide (AAO) films play an important role in nanotechnology due to their easily adjustable morphological properties and wide range of applications. Thus, a deep and systematic characterization of ...

The anodic oxidation of aluminium is an electrochemical technique that allows obtaining nanostructures with easily adjustable morphology depending on the synthesis variables, for its application in medicine, engineering, ...
Estudio de la solidificación de una prótesis de cadera fundida en acero inoxidable austenítico Astm f745
(Laboratorio de Entrenamiento Multidisciplinario para la Investigación Tecnológica, 2020-04-11)
La solidificación de una prótesis de cadera ha sido estudiada mediante curvas de enfriamiento en dos regiones distintas: la zona próxima al acetábulo, de mayor masa, y el vástago distal, que es la zona más fina de la ...
Evaluation of the influence of texture and microstructure of titanium substrates on TiO2 anodic coatings at 60 V
(Elsevier, 2017-09-01)
The current paper analyzes the influence of texture and microstructure of Ti substrates on morphology and color of titanium dioxide coatings obtained by anodic oxidation. Substrates of Ti grade 2 and Ti grade 5 with different ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...
