FIELD: metallurgy.
SUBSTANCE: method of production of surface-nanostructured metal includes metal restoration from initial metal containing solid material by treatment by vapours of silicone liquid for rendering water-repellent in form of low-molecular oligo organohydridesiloxanes with further annealing in dehydrated natural gas. Metal restoration is performed at temperature from 320 to 400°C using natural gas as gas carrying vapours of silicone liquid for rendering water-repellent, and annealing is performed at temperature from 500 to 695°C.
EFFECT: reduced method toxicity.
