METHOD OF METAL SURFACE SUPER HYDROPHOBIC PROPERTIES MAKING Russian patent published in 2016 - IPC B23K26/364 B82B3/00 H01L21/268 H01L31/18 

FIELD: technological processes; metallurgy.

SUBSTANCE: invention relates to method of metal surface super hydrophobic properties making. Said surface is exposed to focused beam of pulsed laser radiation with pulse duration in nanosecond range, said beam is displaced relative to said surface at predetermined law. Selected said laser radiation characteristics and said relative displacement parameters so, that to form multimodal roughness on said surface with dimensions of simultaneously in nanometer and micrometer ranges. Modifying said surface with low surface energy substance, water repellent.

EFFECT: technical result consists in high efficiency of surface texturing and enabling formation of multimodal roughness super-hydrophobic state with characteristic dimensions simultaneously in nanometer (nanometers and/or tens of nanometers) and micrometer (tens and/or hundreds of micrometers) ranges.
