METHOD OF FORMING COMBINED SUPERHYDROPHOBIC SURFACE STRUCTURE Russian patent published in 2022 - IPC C09K3/18 B05D3/12 B05D5/02 B05D5/08 C23C16/26 C01B32/15 B82Y40/00 B81C1/00 F28F13/04 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used for stabilization of drop condensation on metal surface and its protection against corrosion. To form a superhydrophobic structure of a metal surface, a microtexture with a characteristic size of 70–80 mcm is first pushed with spherical particles, then carbon nanoparticles with size of 5–100 nm are deposited from gas phase, thus forming a structure with combined roughness. Obtained surface is hardened by impregnation with 0.1 % solution of synthetic rubber in acetone.

EFFECT: increased heat release at drop condensation on hydrophobic surface, simplified technology of hydrophobic coating formation due to exclusion of drying and laser treatment.
