Patent

CA 2357039

The present invention relates to a method for processing solid-state materials that involves forming pores having a maximal cross-section of 100 nm in the surface layer of said material. The pores are further filled with threads made of a different material or made of the same material. It is thus possible to improve a whole series of characteristics of the material, mainly concerning its resistance and acoustic losses. This invention can especially be used in the production of piezo-ceramics.

Cette invention concerne un procédé de traitement de matériaux monolithiques qui consiste à former des pores d'une section maximale de 100 nm dans la couche de surface dudit matériau. Ces pores sont ensuite remplis de fils faits d'un autre matériau ou de ce même matériau. On obtient ainsi une amélioration de toute une série de caractéristiques du matériau, notamment en ce qui concerne sa solidité et les pertes acoustiques. Cette invention peut tout particulièrement être utilisée dans la fabrication de piézo-céramiques.
