Abstract
A method of producing substrate having an antimicrobial surface by thermally spraying the surface with metals such as copper and alloys of copper, silver and alloys of silver, zinc and alloys of zinc, tin and alloys of tin and combination thereof and thereafter abrading the sprayed surface to give the surface antimicrobial properties.
Claims23
A method of providing a substrate with having an antimicrobial surface, the method comprising:
- thermally spraying a metal onto a surface of a substrate, the metal being any one of copper and alloys of copper, silver and alloys of silver, zinc and alloys of zinc, tin and alloys of tin, and any combination thereof to produce a thermally sprayed metal coat having surface cavities with a depth;
- and
- mechanically abrading an outer surface of the thermally sprayed metal coat to reduce the depth of the cavities and give an exposed abraded metal surface in regions intermediate the cavities for producing an antimicrobial surface such that microbes left behind on the antimicrobial surface are killed in an absence of a liquid solution.

A method of providing a substrate with an antimicrobial surface, the method comprising mechanically abrading a substrate having an outer thermally sprayed metal coat having surface cavities, the metal being any one of copper and alloys of copper, silver and alloys of silver, zinc and alloys of zinc, tin and alloys of tin, wherein the metal coat optionally has a polymer film formed thereon, to reduce the depth of the cavities and produce an exposed abraded metal surface in regions intermediate the cavities for producing an antimicrobial surface such that microbes left behind on the antimicrobial surface are killed in an absence of a liquid solution.
