Abstarct: Alumina or aluminum oxide is one of the most important engineering ceramics. This material has been used in cutting tools, parts resistant to abrasion and corrosion, due to its outstanding mechanical and physical properties. Pure alumina has a very low fracture toughness. This reduces the reliability of produced samples and makes it difficult to be utilized. Adding Stabilized zirconia to alumina yields alumina/zirconia composites with increased fracture toughness. Thin laxyers of ceramic are used in various industries such as industrial machinery and medical industry. Tape casting is distinguished as one of the most important approaches to form thin ceramics films. The purpose of this study is to investigate the application of combined Tape casting-polymer Impregnation method with Polymerized Infusion method for the purpose of producing common alumina/zirconia composites. Using tape casting method, several samples were made. In order to make these samples through this method, first, stabilized zirconia, alumina and a combination of them were prepared considering different parameters to reach an optimum mixture. To produce the samples using combined method, first, a prose laxyer of stabilized zirconia was made using the Tape casting method, and then, the laxyer was soak in aluminum nitrate, and Finally, the samples prepared by the two methods were sintered at high temperature. Using Archimedes method, the density of samples was measured. Hardness was determined using microhardness and nanoindentation tests. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to study the phases and microstructure of the samples. Density data showed that samples had a dense structure. Their hardness results revealed that hardness would increase by increasing the amount of stabilized zirconia fraction. Samples made using combined method had the most hardness (14 GPa) and Fracture toughness (7.2 MPam1/2) across all the samples. The most contact stiffness (299 µN/nm) and Young module (326 GPa) belonged to the samples made using combined method. XRD results showed existence and also the approximate content of Stabilized zirconia and alumina phases. Finally, According to SEM micrographs of the samples, the impregnated sample had the least porosity and the most structural uniformity. This study demonstrates the potential of the combined technique as a new method in producing alumina/zirconia thin films.
