The combination of different mechanisms of matrix strengthening by large and small filler particles led to the creation of gradient multilayer CEP with “straight” and “inverted” gradients of the structure along the thickness of the coating layer. The use of CEP gradient type increases their wear resistance from 4 to 7 times, which is due to the favorable distribution of internal stresses, especially when using CEP with a “direct” gradient of their structure. Given that cavitation-erosion wear resistance is due to two factors: corrosion and mechanical, it is necessary to investigate not only physical and mechanical characteristics, but also changes in their electrochemical characteristics and corrosion resistance depending on the technological parameters of electrolysis, nature and geometric particle size of the filler. etc.\u00a0The aim of the work is to study the cavitation-erosion wear resistance of formed composite electrolytic coatings (CEC) with silicon carbide (SiC) particles of different geometric sizes and different volume content in the nickel matrix in neutral, acidic and alkaline media. It is shown that CEC with SiCnano<\/sub> and SiC5<\/sub> particles on average 6 times increase the wear resistance of steel 45 normalized in hard water, 11 times in 3% NaCl solution and more than 16 times in acidic environment. Studies have also shown that with increasing corrosion activity of the environment, the efficiency of CEC increases, and increasing the size of SiC particles reduces the cavitation and erosion resistance of the coating. It was found that increasing the volume content of SiCnano<\/sub> and SiC5<\/sub> particles in the Nickel matrix increases the cavitation-erosion resistance of CEC in all media. The effectiveness of the effect of SiCnano<\/sub> and SiC5<\/sub> particles on the wear resistance of CEC in 3% NaCl solution is manifested at their volume content of the matrix Ca<\/sub>\u00b310%. For SiC50<\/sub> and SiC28<\/sub> particles, the maximum values of cavitation-erosion wear resistance in all studied media are achieved when their content in the nickel matrix Ca<\/sub>=22\u202625%. In the future, it is necessary to investigate the influence of the stress-strain state of the hardened surface, the distance between SiC particles on the physicochemical and tribological characteristics of CEC.
