| Abstract Scope |
With the rapid diversification of both powder generation methodologies and printing techniques, the need to understand the characteristics of metal powders is of increasing importance. Here, we describe the use of computer controlled scanning electron microscopy (CCSEM), at the Neighborhood 91 ecosystem, for the statistical characterization of manufactured powders used in cold spray printing. Traditionally, powders are characterized with particle size distributions measured with laser light scattering methods. In this discussion, we show the added utility of CCSEM to provide supplemental information regarding the characteristics of metal powders. The metrics developed have been beneficial in addressing the quality and flowability of powders and have aided in streamlining the powder manufacture to printed part lifecycle at Neighborhood 91. |
