WebbNitinol alloy films can be used to make micro-drivers with wide application prospects. Nitinol alloy films with a thickness of less than 20µm can be prepared by vapor deposition. Ion plating method is not suitable for the preparation of nitinol alloy films because the chemical composition cannot be well controlled. Webb7 sep. 2016 · In this paper, we introduced a thin film nitinol (TFN) as an alternative graft material and evaluated the growth behavior of endothelial cells (EC) both qualitatively and quantitatively. As a proof-of-concept study, both untreated nonpatterned film (TFN) and surface treated TFN (S-TFN) materials were used. We compared the adhesion, growth, … WebbNo signs of corrosion were present on thin film nitinol samples after immersion in Hank's solution for one month. Finally, organ and tissue samples explanted from four pigs at 2, 3, 4, and 6 weeks after thin film NiTi implantation appeared without disease, and the thin film nitinol itself was without thrombus formation. nxn 2018 boys race
