Abstract
The technological effect of porous implants in biomedical applications has stepped up the look for advanced shaping tools. The present work was mostly concerned on create and control on porosity and surface roughness of zirconia structures that production by electrophoretic deposition (EPD) technique. Distilled water is utilized in this study to help to create the porosity and increase the surface roughness by its addition in little amounts to ethanol suspension. The obtained porous structures were investigated using SEM and AFM analyses. The addition of water affected the properties of the alcohol suspension, reducing the pH and increasing the dielectric constant. The results show that even adding a small amount of water to an electrolytic suspension leads to gas release on the electrode. The resulted zirconia structures showed the 1 ml water addition was the ultimate value to create uniform pores on the deposited part in the case of 0.5 g zirconia powder volume.
