Abstract: A thin film metallic glass coated needle includes a needle body, a needle head and a thin film metallic glass in amorphous structure and formed on a surface of the needle head and a surface of the needle body to reduce a surface energy and coefficient of friction. The thin film metallic glass is a titanium based comprising 35-45 at % titanium, 5-15 at % zirconium, 32-42 at % copper, 1-11 at % niobium and 2-12 at % cobalt.

Abstract: A diaphragm structure is used for an audio signal output device. The diaphragm structure includes a film substrate, a polymer fiber structure and a thin film metallic glass. The film substrate includes a first surface and a second surface opposite to the first surface. The polymer fiber structure is combined with the first surface of the film substrate. The thin film metallic glass is formed on at least a part of the second surface of the film substrate.
