▎ 摘  要

NOVELTY - Procedure consists in galvanic sedimentation of chromium coating from electrolyte. Also, into electrolyte there is introduced nano-carbonic material with amount of graphene layers as many, as 30, external diameter of fibres from 10 to 60 nm and length of fibres mot less, than 2 mcm at contents of structured carbon as high, as 95 % at amount of 0.03-0.08 g/l. Further, electrolyte is treated with ultra-sound. USE - Metallurgy. ADVANTAGE - Increased micro-hardness of chromium coating at reduced expenditures for disperse materials introduced into electrolyte. 3 cl, 1 tbl, 1 ex
