Abstract:
1. A method of depositing a nanocomposite coating onto a metal or substrate, including the steps of: (a) providing at least one metal or metal alloy substrate; (b) depositing stainless steel on said at least one substrate; (c) depositing a carbide or nitride of a first metal on said at least one substrate; and (d) allowing a nanocomposite coating of said stainless steel and carbide or nitride of said first metal to form on said at least one substrate, wherein the nanocomposite coating includes grains of stainless steel crystals along whose grain boundaries a nano-structure of molecules of metallic carbide or metallic nitride is formed interstitially, and wherein said substrate is made at least principally of stainless steel, copper, aluminum, magnesium, titanium, or an alloy of any of these metals.
