Macroestructuras de solidificación versus parámetros térmicos y electroquímicos en aleaciones zinc-aluminio (za)
Abstract
Los materiales bimetálicos se fabrican por una diversidad de razones, entre ellas podemos mencionar el reemplazar aleaciones costosas, mejorar el aspecto superficial, obtener mayor resistencia mecánica, resistencia al desgaste o a la corrosión. La presente investigación se realiza en aleaciones zinc – aluminio (Zn-4%Al, Zn-16%Al y Zn-27%Al) en sus diferentes estructuras (columnar, equiaxial y con transición, TCE), a fin de estudiar la vinculación entre los parámetros de solidificación, estructurales y de resistencia a la corrosión de las mismas. Los resultados son fuertemente dependientes de la concentración de aluminio en la aleación, como así también del tipo de estructura que las mismas presentan.Downloads
