Sample preparation and research of amorphous composite material for transmission electron microscope

Abstract

Abstract The two preparation methods of amorphous composite TEM samples, electrolytic double spray thinning and ion thinning, are studied. In addition, an improved ion thinning method is used to successfully prepare a metastable brittle amorphous composite TEM sample. The TEM sample prepared by the ion thinning method has a large thin area near the interfaces in composites, which lays a solid foundation for further research on the interface principle of composite materials, and also provides reliable data support for optimizing the preparation process of the composite materials.
