| Popis | Electrophoretic deposition (EPD) of plasma pre-treated Al2O3 and ZrO2 powders results in ceramic layers of substantially improved deposit homogeneity. To evaluate the practical applicability of this phenomenon, we report on the magnitude and dynamics of undesired gradual deterioration on plasma treatment – the ageing effect. Powders samples were treated by diffuse coplanar barrier discharge and sequentially evaluated for their EPD performance for the time span of 30 days. The ageing effect has no detrimental effect on deposition rate at least for the first 14 days from the plasma treatment. During the whole testing period of 30 days, the improved coating uniformity remained unaffected. |
