Optimised sintering schedule of conventional sintering + HIPing allowing full densification of medical grade Al2O3-ZrO2 powder based FGM discs

Bodycote and K.U.Leuven optimised the sintering schedule of conventional sintering + HIPing allowing full densification of medical grade Al2O3-ZrO2 powder based FGM discs. The densification cycle was also applicable for the sequentially slip casted components from IJS. Pressure less sintering is performed for 1 h in air at 1550°C, followed by post-HIPing at 1390°C for 20 min in 140 MPa Ar. The final grain size of the Al2O3 surface layer of the components remains below 2 µm.
