<p>A method of coating a metallic article having an at least part-metallic s urface comprising a first metal, with a surface having a pre-determined wett ability, the method at least comprising the steps of: (a) coating at least a part of the metallic article with a layer of a second metal to provide a me tal-metal bonded surface, said surface being rough either prior to or becaus e of step (a); and (b) contacting the metal-metal bonded surface of step (a) with a material to provide the surface having the pre-determined wettabilit y. The first metal may be one or more of the group comprising: iron, zinc, c opper, tin, nickel and aluminium, and alloys thereof including steel, brass, bronze and nitinol for example. Preferably, the second metal is coated onto the first metal using electroless Galvanic deposition. The nature of the co ated metallic article is non-limiting, as the ability of the present inventi on is to provide a tailored surface with a pre-determined wettability thereo n, including superhydrophobic and superhydrophilic wettability. This allows the invention to be capable of application to a wide range of metal types us ed in different fields.</p> |
