Anti-microbial coated devices and methods for making same

摘要

An anti-microbial coated device includes a device sized and configured for use in a microbe-contaminating environment. The device includes a substrate having a surface configured to be exposed in the microbe contaminating environment. A cold-sprayed anti-microbial coating is deposited on at least a portion of the surface of the substrate. The anti-microbial coating includes fused metal particles and having a thickness in a range from 100 nm to 1 mm.
