Abstract
A method for treating a surface of a metallic structure, the metallic structure being made of a first metallic material, the method including the steps of: (a) releasing metallic ions from the surface of the metallic structure; and (b) depositing a nano-structured metallic layer onto the surface of the metallic structure from the released metallic ions, wherein the nano-structured metallic layer includes uniform nanoparticles.

A method for treating a surface of a metallic structure, the method comprising the steps of:
- (a) releasing metallic ions from the surface of the metallic structure, the metallic structure comprising a first metallic material selected from the group consisting essentially of silver metal, a silver alloy, and a combination thereof;
- and
- (b) depositing the released metallic ions onto the surface of the metallic structure to form a nano-structured metallic layer, wherein the nano-structured metallic layer includes uniform nanoparticles, wherein the size of the nanoparticles is in a range between 100 to 600 nm;
- wherein the method is performed using an electrochemical cell comprising a first electrode, a second electrode, and an electrolyte in electrical connection with the first electrode and the second electrode, wherein the metallic structure to be treated is connected as the first electrode, and wherein prior to step (a) the electrolyte does not contain the metallic ions to be deposited.
