Fabrication and mechanical properties of ZrO2–Al2O3–SiC(w) composites by oscillatory pressure sintering
Source abstract
Abstract
Abstract Tetragonal zirconia polycrystalline (TZP) ceramics have been considered as the important structural materials in many key technology fields, but some of their mechanical properties do not meet the requirement under the extreme environmental conditions. In this work, SiC whiskers and Al2O3 particles were used as reinforcement additives to synergistically toughen TZP ceramics, and a newly developed oscillatory pressure sintering (OPS) technique was employed to fabricate the new zirconia-based ceramics. For comparison, the traditional hot pressing (HP) method was also used to prepare these composites. The results showed that with 15 vol% SiC whiskers addition, the toughening mechanisms such as whisker bridging, whisker pulling-out, crack deflection, and crack branching appeared apparently, thereby improving fracture toughness of such composites. In contrast to HP, OPS can eliminate defects, improve densification, obtain more uniform microstructure, and significantly enhance mechanical properties of the composites.
