Manufacture strengthening of corundum-zirconium ceramic in ultrasonic compacting of ultradisperse powders
The effect of ultrasonic compacting (USC) of ultradisperse oxide powders of the ZrO2-Al2O3 system on sintering of the ceramic was analyzed. It was shown that USC increases the density of pressed samples to 55% of the theoretical density of the ceramic. The sintering temperature of the corundum-zirconium ceramic was reduced by 200–300°C with the USC method. The ceramic obtained had improved strength properties.
