Effects of Gelcasting Parameters on the Solids Loading of Ti-6Al-4V

Abstract:

Ti-6Al-4V green body was processed by gelcasting. Effects of the powder morphology, dispersant and pH on the solids loading were investigated. The morphological properties were investigated by SEM. The results show that the powder morphology is the overriding factor in slurry processing. Slection of dispersant and pH are another two critical factors affecting the solids loading by a percentage of 2 to 4. With optimum conditions: spherical powders, 1.5 wt.% ammonium citrate as the dispersant and pH=11, the green body with high solids loading of 59.4% was prepared.
