Influence of Planetary Ball Mill Parameters on Powder Flowability of AlSi10Mg with Niobium Carbide Using Central Composite Design (CCD)

The hypoeutectic aluminum alloy (AlSi10Mg) is a well-known candidate material used predominantly for its processability and inherent characteristics in metal-based additive manufacturing. Besides, transition metal carbide, such as niobium carbide (NbC), added to the AlSi10Mg, enhancing mechanical properties preferably wear resistance matrix. However, manufacturing, mixed powder’s flowability prerequisite determining final of specimens. In this study, powder analysis was carried out through regular mixing AlSi10Mg with varying weight percentage NbC conducted planetary ball mill different time, speed, composition following Central Composite Design (CCD), total 20 experiments. Here, preferred retain morphology (spherical shape) instead milling, which contributes degradation shape size. Finally, based on combined apparent density (AD), tapped (TD), static angle repose (SAoR), powders (AlSi10Mg + X % NbC) were evaluated. optimum combination X% attained composite desirability criteria.
