Abstract
The metallic glassy alloy powders for antibacterial coating are mechanically alloyed mixtures of copper, titanium, and nickel nanoparticles. The nanoparticles are alloyed by ball-milling to form glassy, metallic powders. The alloy preferably has a copper:titanium:nickel atomic percentage ratio of about 50:20:30, referred to herein as CuTiNi. The powdered alloy is applied to a suitable substrate, such as stainless steel medical instruments, by cold spray powder coating. The coated substrate exhibits antibacterial properties compared to an uncoated substrate.
