We studied the composition of electrochemical titanium and silicon zinc dioxide coatings, as well as the special aspects of their morphology and corrosion resistance. It is found that the particles of TiO2 are included into the zinc matrix. Share of dispersed phase in CEC grows with increasing the concentration of particles in the suspended electrolyte. It is shown that the SiO2 particles are not included into the coating, inhibiting the process of cathodic reduction of zinc. It is also found that crystals on all the coatings obtained have a hexagonal structure, while introducing the dispersed phase particles leads to the plating structure refinement. It is shown that including the TiO2 particles leads to forming the coatings of better corrosion resistance.
