Composite electrolytic coatings (CECs) precipitated by pulse current from nickel sulphate electrolyte containing ultrafine diamonds (UFDs) is investigated. The influence of parameters of pulsed current during the electrolytic deposition of nickel coatings on the structure and mechanical properties of the CECs as well as on the content and distribution of the co-deposited nanodiamond particles within the metal matrix is considered. The results show that the use of the joining of UFDs with modified nickel surface increases microhardness and wear resistance of nickel coatings.

Key words: mechanical properties, ultrafine diamond particles, composite electrolytic coating, pulse current.
