Abstract
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.
Claims8
A method for minimizing contamination of food products using an anti-microbial food processing apparatus, comprising:
- providing a food processing facility including food processing machinery having structure that contacts food materials during food processing, the food processing facility comprising one or more surfaces having a substrate comprising a polymer, a natural fiber, or concrete, the substrate having a cold-sprayed anti-microbial coating deposited on at least a portion of the surface area, the anti-microbial coating comprising a continuous layer of copper having a thickness in a range from 100 nm to 5 mm;
- exposing the anti-microbial coating to a microbial load, the antimicrobial coating at least partially killing the microbial load.
A method as in claim, wherein the anti-microbial coating includes brass silver, alloys thereof, or combinations thereof.
A method as in claim, wherein anti-microbial coating is allowed to kill at least 95% of the microbial load.
