Comportamiento frente a la corrosión del material compuesto 2124/SiC

Abstract

[EN] A comparative study was performed on the corrosion behaviour of an aluminium matrix composite reinforced with silicon carbide particles, obtained by powder metallurgic. The 2124/SiC material was heat treated using T4 and T6 procedures. The T6 heat treatment induced the formation of several intermetallics and reducing the corrosion resistance. The silicon carbide particles did not have a cathodic behaviour as compared with the aluminium matrix. However, these particles produced a diminution in the corrosion resistance due to the formation of more active zones in the matrix/reinforced interface. These ceramic particles caused intermetallic precipitation and deformation originating in the surrounding zones localized corrosion.

[ES] Se realiza un estudio comparativo del comportamiento frente a la corrosión de la aleación de aluminio 2124 reforzada con partículas de carburo de silicio, obtenida por pulvimetalurgia y con tratamientos térmicos T4 y T6. Los resultados experimentales muestran que el tratamiento térmico T6 induce la formación de numerosos intermetálicos que reducen la resistencia a la corrosión. Las partículas de carburo de silicio no tienen un comportamiento catódico con respecto a la matriz de aluminio, sin embargo, disminuyen la resistencia a la corrosión, ya que generan zonas más activas en la interfase matriz/ refuerzo, debido a la acumulación de dislocaciones, tensiones residuales y a la precipitación de intermetálicos.

Los autores desean expresar su agradecimiento a la Comisión Interministerial de Ciencia y Tecnología (CICYT) por la financiación del proyecto MAT2001-1732-C02 y a la Unión Europea por el proyecto BRITE-EURAM no BE96-3168.
