dc.description.abstract In this work, the main purpose is to develop different composites of Al2O3-Mo varying the volume percentage of materials to see their variation of properties and to find the best composition of metal and ceramic in order to get the best results. As a short way to explain the process to develop the composite, we could say that these were the main stages of the production: 1. For obtaining a homogeneous ceramic-metallic mixture of powders we milled alumina and molybdenum powders. 2. The mixture is milled for 15, 30, 60, 90, 120, 180 and 240 minutes. Different samples of the mixture will be taken and analyzed in SEM and XRD. 3. After finding the right milling time, different pieces of the mixtures will be made by sintering by the SPS process. If the pieces are correctly done, we will make some mechanical tests to analyze its properties. 4. An evolution or properties will be made to analyze the consequences of the volume percentage of molybdenum in the composite. 5. Discussion of the results.
dc.description.abstract El presente trabajo se centrará en la obtención del material compuesto metálico-cerámico formado por alúmina y molibdeno, así como su estudio de propiedades y variación de éstas en función de las proporciones de ambos constituyentes. De una manera breve, el proceso llevado a cabo en este proyecto ha sido el siguiente: 1. Molienda de polvos de alúmina y molibdeno en un molino mecánico. 2. Estudio del tiempo óptimo de molienda. 3. Distintas composiciones de polvos compuestos son sinterizados mediante Spark Plasma Sintering en temperaturas y tiempos variables. 4. Estudio de propiedades y análisis de resultados.
