Original abstract

The similar electrophoretic mobility of Al2O3 and ZrO2 in the isopropanol suspensions containing monochloracetic acid enabled a controlled preparation of layered and particle composites Al2O3/ZrO2 as well as functionally gradient materials with gradual composition transition from Al2O3 to ZrO2. In view of the negative charge of Al2O3 and ZrO2 particles in the isopropanol suspensions used, all the prepared types of composite 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. Phenomena related to the deposition kinetics of these composites as well as some properties of as-sintered composites are described in the paper.

Czech abstract

Podobná hodnota elektroforetické pohyblivosti Al2O3 a ZrO2 v izopropanolových suspenzích obshujících kyselinu monochloroctovou umožnila řízenou přípravu vrstevnatých a částicových kompozitů Al2O3/ZrO2, stejně jako funkčne gradientních materiálů s postupnou změnou složení od Al2O3 k ZrO2. Díky negativnímu náboji Al2O3 a ZrO2 částic v použitých suspenzích byly všechny kompozity depozitovány na anodě, nebyly proto ovlivněny možnou elektrolýzou rozpouštědla, což přispělo k jejich bezdefektní a neporézní struktuře. V článku jsou také popsány některé jevy spojené s kinetikou depozice částic, a také některé vlastnosti slinutých kompozitů.
