Faststoffmateriale

摘要

A process for the treatment of solid state materials is described, in which pores with a cross section of up to 200nm are formed in the surface layer of the material, and these pores are filled with filaments of another material or of the same material. This produces an improvement in a number of characteristics of the material, including strength and acoustic losses. The invention may be used most successfully in the production of piezo-ceramics.
