The composition of electrochemical coatings of nickel-zirconium dioxide, the peculiarities of their morphology were investigated. It was shown that depending on the dispersion and the method of preparation (plasma-chemical method and deposition method) of the dispersed phase, the content of inclusions in coatings varies from 0.2 to 1%, in the case of the plasma-chemical method and from 0.3 to 2%, in the case of particles obtained by the deposition method. Nickel-zirconium coatings are characterized by increased microhardness, corrosion resistance, and wear resistance compared to control precipitates by 1.4; 2.4 and 1.2 times respectively.
