Originální abstrakt

Electrophoretic deposition is an experimentally undemanding and comparatively cheap technique enabling the formation of deposits from particles of nanometric dimensions to particles of several micrometers in size. Electrophoretic deposition can yield layers of a wide range of thickness, from several nanometers to several millimeters. Usually, electrophoretic deposition of Al2O3 and ZrO2 in aqueous medium is described in the literature. However, using aqueous solutions results in the electrolysis of water, with gaseous hydrogen generated on the cathode and oxygen on the anode. These gases form bubbles in the deposit, reduce its density and prevent the deposit from adhering to the electrode. On the other side the disadvantage of using suspensions with organic solvents is that the particles are more difficult to stabilize; at the same time suspension stability is the limiting factor with respect to obtaining a deposit of high density. The aim of the present work was therefore to prepare Al2O3 and ZrO2 deposits from isopropanol suspensions stabilized with monochloroacetic acid.
