Laminated alumina/zirconia ceramic composites prepared by electrophoretic deposition
Original language description
The electrophoretic deposition of alumina and zirconia powders from isopropanolic suspension in the presence of monochloroacetic acid was studied in the constant-current regime. The different levels of electric current during deposition from 250 A to 48mA were used. The green density of the deposit depends on the current density and then on the particle velocity during deposition, reaching values from 58% to 61% according to the electric current used. It was found that the lower the green density of the green deposit, the larger the pores. The low green density led to low ?nal ?red density and subsequently to the low Vickers hardness HV5 ranging from 2000 to 1650 depending on electric current used. Based on these ?ndings microlaminates having variousthickness ratios to achieve different residual stress levels were prepared consisting of alternating layers of alumina and zirconia.
