Abstract

  We found that the laser irradiated surface of copper substrate becomes fine structure, which we named "surface fine crevice structure". Liquid bismuth on “surface fine crevice structure” of copper substrate occurs “unusual wetting”. In the present work, we investigated the wettability of “surface fine crevice structure” of iron substrate by liquid tin, indium and bismuth. “Unusual wetting”appears on laser irradiated surface of iron substrate in case of liquid indium and tin. Whereas, liquid bismuth does not show “unusual wetting” on laser induced iron surface under the present experimental conditions.
