Utilization of Sodium Flame Synthesis for the Formation and Deposition of Pure Metal Materials for Applications in Additive Manufacturing

<p>Advanced material classes, such as high temperature alloys, ceramics, and refractory materials have become a key area of focus for expansion in the realm of additive manufacturing. Factors such as high melting points, material homogeneity, and physical properties such as ductility limit the application of popular additive manufacturing methods to these material classes. By utilizing sodium flame synthesis and deposition (SFD) technology, nanoparticle materials can be synthesized via combustion in a laminar co-flow diffusion burner and impacted such that the deposits can be used to manufacture designed components. By using the applicable precursor materials of metal chlorides and elemental sodium as a reducing agent, vapor-phase combustion is shown to produce titanium and niobium particles that impact to form high purity line deposits. From these experiments, the groundwork is laid for the development of production methods of more complex materials and higher quality and more complex deposits.</p>
