Estudio del eutéctico Al<sub>2</sub>O<sub>3</sub>-ZrO<sub>2</sub> (3% Y<sub>2</sub>O<sub>3</sub>) dopado con TiO<sub>2</sub> obtenido por solidificación direccional

Abstract: An study of directionally grown samples of the eutectic composition in the Al 2 O 3 -ZrO 2 (3 mol% Y 2 O 3 ) system, with small TiO 2 additions (1 wt%), is presented. The microstructural changes induced by this addition are analysed using SEM (EDX) techniques. The mechanical changes, when TiO 2 is added, are studied by measuring the flexural strength by three point bending. Also, the toughness is determined by Vickers indentation method. When slow growth rates (10 mm/h) are used, interpenetratred and homogeneo… Show more

“…laser floating zone (LFZ) melting technique. [2][3][4] The Bi based superconducting materials textured using the LFZ technique show very well aligned crystals, with their a-b planes parallel to the growth direction. With this alignment and particularly in the case of the Bi 2 Sr 2 CaCu 2 O 8zd (Bi-2212) superconductors, current flow can achieve very high values without resistive losses.…”

“…Para algunos de estos casos, la tecnología láser ofrece una moderna herramienta escasamente utilizada en la industria cerámica. La mayor parte de los trabajos encontrados en la literatura referentes tanto a la fusión láser como a la ablación de materiales cerámicos se han tratado esencialmente sobre óxidos puros, nitruros, carburos o mezclas de estos, así como de ladrillos de arcilla en el caso de los soportes cerámicos [Bäuerle;Rubahn;Sappey;Steen;Restrepo;Black;Quintero;Díez, 2007;Larrea;Mendes]. Existe también bibliografía (artículos y patentes) que versan sobre la utilización de láseres de CO 2 en el procesado de superficies cerámicas [Peligrad; Young; Samant; Fields].…”
