| Abstract: | Densification behavior and mechanical properties of Al 2O 3-ZrO 2-SiC composites were investigated by RBAO technology (Reaction Bonding of Aluminum Oxide) and by comparing different starting powders. The composition with fine Al 2O 3 and coarse SiC exhibited the fastest densification and highest final density. This material was sintered for a short time and then HIPed to inhibite Al 2O 3 grain growth, which resulted in a density of nearly 100% and a strength of 760 MPa. |
