Popis: In this work we have synthesized Ti3C2TX MXene powder and studied its structure. Composite electrochemical coatings (CECs) of Ni-Ti3C2TX MXene were obtained from a sulfate– chloride bath in the galvanostatic regime. The microstructure of CEC was researched using X-ray phase analysis and scanning electron microscopy methods. It has been established that a Ni–Ti3C2TX MXene CEC microhardness rises by about 1.80 times compared with electrolytic Ni without a dispersed phase. For corrosion research, different corrosive media is applied. The corrosion–electrochemical behavior of Ni–Ti3C2TX MXene CECs by the chronovoltamperometry method in 0.5 M H2SO4 solution has been investigated. Trials in 3.5% NaCl have shown that Ti3C2TX MXene inclusion into the matrix of the electrochemical Ni results in a decrease in the corrosion rate by 1.60–1.75 times. These effects are due to the addition of Ti3C2TX MXene into the nickel matrix and the formation of CECs with a strengthening fine-grained structure.
