Аннотация: One of the most promising ways of periodic and/or nonperiodic nanostructure formation on implants'material surface, particularly on a titanium surface, providing the implants with the desired adhesive andwettability properties, is direct laser nanostructuring which uses only a laser beam with no atomic-forcemicroscope's ancillary needle or masks in order to form surface nanorelief. In the present paper, the model of ananostructure formation on a solid surface by microsecond laser pulses melting the material is described. It is shownthat the typical size of the surface nanostructure formed depends on the laser wavelength, pulse energy, pulserepetition rate, and pulse duration. Within the present study a series of six experiments devoted to direct lasernanostructuring of titanium and copper surfaces was carried out. Besides, the effects of nanoroughness on thecontact and sliding angles on hydrophilic surfaces were studied theoretically and experimentally.
