The wettability of solid surfaces is very important to fundamental research and practical application.Inspired from species in nature a variety of bionic surfaces with super wettability have been fabricated by lithography,templating,plasma treatment and laser methods.Recent years,metal bionic materials used in heat transfer and their enhancement mechanism have been promising topics,for example superhydrophilic surface was used in boiling enhancement [1]dropwise condensation [2]and heat exchangers[3]and so on.But most metal superwettability surfaces used in heat transfer field were uniform while hybrid wetting substrates always were non-metal like silicon wafer.
