Diffusion Bonding of A12O3 and Si3N4 Ceramics by Hiping
Diffusion bonding of Al2O3 and Si3N4 attempted using high pressure technology. The high pressure and temperature conditions were 100 MP a and 1650°C for HIPing and 3.0 GPa and 1650°C for high pressure experiments. The results of SEM observations and Vickers microhardness measurements for the interface of the bonded specimens suggested that the strong bonding between these sintered ceramic bodies was completed and that the high pressure technique is one of the useful methods for diffusion bonding of ceramics.
