Abstract
<p>We investigated the detailed mechanism of the unusual wetting of liquid metal bismuth on the surface fine crevice structure of copper metal created with laser-irradiation by focusing on the wetting state during the course of wetting. It was observed that liquid bismuth infiltrates into the fine pore and the interspaces on the surface fine porous structure, and wets on the surface fine crevice structure itself ahead and behind the wetting front, respectively. This revealed that the unusual wetting on the surface of the fine crevice structure proceeded through a transition from microscopic wetting to macroscopic wetting.</p>
