Fabricación de materiales compuestos con microestructuras complejas y propiedades mejoradas a partir de suspensiones

Abstract

[ES]: El procesamiento coloidal ha demostrado su eficacia en la fabricación de materiales cerámicos con una gran variedad de formas y tamaños y microestructuras complejas. Los métodos coloidales suponen la preparación de suspensiones estables y homogéneas del material a conformar, por lo que el control de la estabilidad es fundamental. De forma análoga, los polvos metálicos y las mezclas cerámica- metal se pueden procesar por vía coloidal si se asegura la estabilidad y se evitan o controlan la sedimentación, por una parte, y la disolución y oxidación, por otra. En este trabajo se muestran algunos ejemplos de fabricación de materiales cerámicos y compuestos mediante una aproximación coloidal y se discuten las ventajas de algunas técnicas de conformado sencillas, económicas y reproducibles. Todo ello contribuye a la obtención de materiales más densos y homogéneos, con microestructuras más finas y uniformes, y por tanto, con mejores propiedades de comportamiento.

Colloidal methods require the preparation of stable, homogeneous suspensions of the material to be shaped, so that the control of stability is fundamental. cerámicos con una gran variedad de formas y Similarly, metal powders and ceramic-metal mixtures can be succesfully processed by colloidal routes if sedimentation, on one hand, and dissolution and oxidation, on the other hand, are avoided or controlled. In this work some examples of the manufacture of ceramics and composites through a colloidal approach are shown, and the advantages of some simple, economic and reliable shaping techniques are discussed. It is demonstrated that denser and more homogeneous materials with finer and more uniform microstructures and hence, with cerámicos y compuestos mediante una better behavioural properties, can be obtained.
