Abstract

Composite electrochemical coatings (CECs) based on nickel and Ti3C2Tx MXene were obtained from a sulfate-chloride electrolyte in galvanostatic mode. Microstructure of these CECs) was studied using X-ray phase analysis and scanning electron microscopy. It was found that the microhardness of nickel–Ti3C2Tx CECs increases by approximately 1.80 times compared to pure nickel. The corrosion-electrochemical behavior of nickel–Ti3C2Tx composite coatings in 0.5 M H2SO4 was studied. Based on tests in 3.5% NaCl, it was found that the inclusion of Ti3C2Tx MXene particles in the electrolytic nickel matrix leads to a decrease in the corrosion rate by 1.60–1.75 times.
