3-ELECTRODE PRODUCTION METHOD OF AMORPHOUS AND NANOCRYSTALLINE FILMS AND FOILS

The production of amorphous and nanocrystalline materials in the form of thin films and foils presents known problems. Thus, for example, fi lms and foils obtained from the liquid state by hardening are characte rized by porosity and roughness. This paper presents the three-electro de production method of amorphous and nanocrystalline metallic alloys which are devoid of these disadvantages. Previously ionized argon is u sed as operating gas. The advantages of this method are high purity an d homogeneity of the films obtained, film production of various materi als and the possibilities for deposition on different substrates.
