Original abstract

Electrophoretic deposition of Al2O3 and ZrO2 powders from isopropanol suspension in the presence of monochloroacetic acid under constant-current conditions was studied. The similar charge and electrophoretic mobility of Al2O3 and ZrO2 in the suspensions was found. Adjusting to properly controlled kinetics of deposition deposits were prepared of pre-defined thicknesses. In view of the negative charge of Al2O3 and ZrO2 particles in the isopropanol suspensions used, the prepared layers were deposited on the anode and thus they were not affected by possible solvent electrolysis, which contributed to their defect-free and low-porosity structure.

Byla studována elektroforetická depozice Al2O3 a ZrO2 prášků z izopropanolových suspenzí za přítomnosti kyseliny monochloracetové a při konstantním elektrickém proudu. Správně řízená kinetika elektroforetické depozice umožnila přípravu bezdefektních vrstevnatých kompozitů s kontrolovanou tloušťkou vrstev.
