The effect of electric conductivity on the structure of ceramic coatings prepared by cathode plasma electrolytic deposition
In the present study, Al2O3 (insulator), ZrO2 (ionic conductor) and (ZnO semiconductor) coatings were prepared by cathode plasma electrolytic deposition (CPED) method on stainless steel substrates. The surface morphologies and cross sections of the coatings were analyzed. The contributions to the el...

| description | In the present study, Al2O3 (insulator), ZrO2 (ionic conductor) and (ZnO semiconductor) coatings were prepared by cathode plasma electrolytic deposition (CPED) method on stainless steel substrates. The surface morphologies and cross sections of the coatings were analyzed. The contributions to the electric current densities during the CPED process were studied. A double dielectric layers model was proposed to systematically study the effect of the electrical conductivities on the coating structures. The results showed that the coating structures and the electrical breakdown mechanism were closely related with the electrical conductivities of the coatings and the gas film. The different structures of the coatings can be attributed to the electric conductivity difference between the coatings and the gas film.
•Al2O3, ZrO2 and ZnO coatings were prepared by CPED method.•The contributions to the current density were analyzed.•A double dielectric layers model was proposed to explain the mechanism.•σ of the gas and the coating were key factors on the mechanism. |
