  • METALLIC FINE STRUCTURE AND PROCESSING METHOD THEREOF
    Publication number: 20140212682
    Abstract: Provided is a method for manufacturing a metal structure in which an array of a plurality of pin arrangements is formed on a surface of a metal, in which the method includes: performing a laser processing along a route between pin regions in which the pins are to be formed on a metal base material to form a dross on the pin regions, and repeating the laser processing. As the dross formed in each pin region is repeatedly cast and recast during the repetitive laser processing, the recast layer is formed in a shape of the pin.
