This study evaluates the effect of growth geometry on the microstructure, morphology, and corrosion resistance of Ti thin films. Three coatings were fabricated by Glancing Angle Deposition (GLAD) using a custom DC reactive magnetron sputtering system [2]. In the first configuration, the target was perpendicular to the substrate (α = 0°). In the second and third, the substrate was tilted at 85° (α = 85°), with the last including a 180° azimuthal rotation to obtain a zigzag morphology. Film thickness and morphology were analyzed by SEM, surface roughness by AFM, and crystallinity by XRD. Corrosion behavior in simulated body fluid was assessed using direct and alternating current electrochemical techniques. Results show improved anticorrosion performance with increasing structural complexity: the inclined film exhibited slightly enhanced corrosion resistance, while the zigzag architecture provided the highest resistance, consistent with previous findings on GLAD-engineered Ti nanostructures. 2026-01-01T00:00:00Z https://accedacris.ulpgc.es/jspui/handle/10553/162827 Título: Mitigation of rockfall hazard along highways by using catchment area design charts, obtained from numerical simulation Autores/as: García González, Cándida I.; Franesqui García, Miguel Ángel; Yepes Temiño, Jorge Resumen: This work is framed within the prior seismic-volcanic crisis before a big eruption. A long period where low intensity tremors cause rockfalls. The main target is to reduce rockfall risks along roads, the cost of their maintenance and the environmental impact. These measures would be really useful in developing countries. The study applies a computer simulation model ( consider 9 different parameters, study different and propose 50 design charts of narrow ditches to restrict rocks from rolling up onto the roadway. 2014-01-01T00:00:00Z https://accedacris.ulpgc.es/jspui/handle/10553/161645 Título: Microstructure and mechanical properties of new Ni Cr and Co Cr dental alloys Autores/as: Jiménez Marcos, Cristina; Mirza Rosca, Julia Claudia; Fratila, Anca; Saceleanu, Adriana 2022-01-01T00:00:00Z https://accedacris.ulpgc.es/jspui/handle/10553/161644 Título: INFLUENCE OF SILICON ADDITION ON THE PROPERTIES OF NEW TITANIUM ALLOYS Autores/as: Jiménez Marcos, Cristina; Brito García, Santiago; Mirza Rosca, Julia Claudia; Simona Baltatu, Madalina; Vizureanu, Petricia 2022-01-01T00:00:00Z
