Pulsed Electrodeposition of Composite Coatings Based on Zinc–Nickel Alloy

详细

Composite electrochemical coatings (CECs) based on zinc–nickel alloy and modified by carbon nanotubes (CNTs) are obtained by pulsed electrolysis. The microstructure and tribological properties of these CECs are studied. It is found that addition of dispersed CNTs into the electrolyte for zinc–nickel alloy deposition results in a 1.35- to 1.65-fold decrease in the friction coefficient of the formed coatings. The electrochemical corrosion behavior of the zinc–nickel–CNT CECs is studied in 0.5 M H₂SO₄ solution.
