Additive Manufacturing (AM) is a disruptive technology that incrementally builds very complex objectsx000D
layer-by-layer directly from a digital file, objects impossible to produce by conventional machining. Advancedx000D
Powders and Coatings (AP&C), is a world leader in fabrication of ultra-high-performance spherical metalx000D
powders engineered for AM and metal spray coatings. AP&C is producing among the best free-flowing andx000D
agglomerate-free spherical Ti-based metal powders, yielding superior control and performance efficienciesx000D
over competition. AP&C constantly desires to further understand the characteristics of their powders for AMx000D
and how powder quality can be further improved to ultimately develop a global understanding between thex000D
powder characteristics and compositions. This relation is strategic to improve their competitiveness andx000D
product portfolio, leading to the ultimate goal of business growth. This proposal will provide baseline answersx000D
regarding the feasibility and complementarity in using a new powder characterization tool: the dynamic anglex000D
of repose (Granudrum) to better understand metal powder motion and rheology as an emerging consensusx000D
reveals that the traditional powder characterization techniques are insufficient to understand the powderx000D
behavior during AM processing. The proposed test matrix will include static and dynamic powder behaviorx000D
properties for three powders: Ti-64, Ti-6242 and Ti-5553. Identification of the relationships between thex000D
extrinsic and intrinsic properties of the proposed powders will be done to identify optimal particle surfacex000D
characteristics mitigating adhesion and cohesion issues. The knowledge will be usable by AP&C to adjust theirx000D
processing parameters to obtain improved powder surface characteristics and help in the development of bestx000D
practices for powder handling by AP&C's customers.
