Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A thin film metallic glass coated needle, comprising: a needle body; a needle head; and a thin film metallic glass being 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. 2 . The thin film metallic glass coated needle of claim 1 , wherein the needle body has a tube, and a surface of the tube is coated with the thin film metallic glass. 3 . The thin film metallic glass coated needle of claim 2 , wherein a material of the needle body is selected from a system consisting of titanium, titanium alloy, aluminium, aluminium alloy, copper, copper alloy, iron, iron alloy, gold, gold alloy and steel. 4 . The thin film metallic glass coated needle of claim 2 , wherein the thin film metallic glass is a titanium-based thin film metallic glass comprising 35-45 at. % titanium, 5-15 at. % zirconium, 32-42 at. % copper, 1-11 at. % niobium and 2-12 at. % cobalt. 5 . The thin film metallic glass coated needle of claim 4 , wherein the thin film metallic glass has a chemical formula of Ti 40 Zr 10 Cu 37 Nb 7 Co 7 . 6 . The thin film metallic glass coated needle of claim 5 , wherein the thin film metallic glass has a hardness larger than 700 HV. 7 . The thin film metallic glass coated needle of claim 5 , wherein the thin metallic glass film has a thickness ranging from 50 nm to 200 nm.
