Electrodeposition of Zinc–Nickel–CNT Composite Coatings in the Pulsed Mode

Resumo

Composite electrochemical coatings based on the zinc–nickel alloy and modified with carbon nanotubes were produced in the pulsed mode. The functional properties (friction coefficient, protective capacity) of the composite coatings were examined in comparison with zinc–nickel alloys without a dispersed phase. It was found that, as carbon nanotube particles are incorporated into zinc–nickel deposits, the sliding-friction coefficient decreases by a factor of 1.30–1.40, and the range of passive-state potentials becomes 1.55–1.65 times wider.
