Abstract—Results of investigations into strengthening the nickel host in the diamond composite electrochem-
ical coating (DCEC) with nanodispersed particles are reflected. Diamond nanopowders of the detonation syn-
thesis, which were introduced into the DCEC through the electrolyte, are applied as the strengthening phase.
As a result, the microhardness of the nickel host increased by a factor of 3, while the durability of tubular drill-
ing tools after the deposition of the diamond coating increased by a factor of 4. The developed technology can
be used when producing a diamond tool for cutting stone, glass, and ceramic materials, as well as to produce
correcting tools.

Keywords: composite materials, sulfate nickel-plating electrolyte, diamond-bearing layer, nanodiamonds, dia-
mond composite electrochemical coating (DCEC), diamond-galvanic drilling tools, dispersion strengthening
