摘要

As part of the study, titanium carbide Ti3C2Tx MXene was synthesized, and its structure was characterized by X-ray phase analysis (XPA) and scanning electron microscopy (SEM). Composite electrochemical coatings (CECs) of nickel–Ti3C2Tx were deposited from a Watts-type electrolyte under stationary conditions (galvanostatic mode). The surface morphology of composite coatings was studied using XPA, SEM, and atomic force microscopy (AFM). It was found that the microhardness of nickel Ti3C2Tx CECs increased more than twice compared to nickel deposits without MXene. The corrosion-electrochemical behavior of nickel–Ti3C2Tx CECs in 0.5 M H2SO4 was studied. Tests in 3.5% NaCl revealed that the addition of synthesized MXene particles into the electrolytic nickel matrix led to a decrease in the corrosion rate of the forming coatings by 1.78–2.00 times.
