Investigation of the Distribution Parameters and Technological Properties of Steel 20X23H18 Powders Produced by Plasma Melting and Centrifugal Spraying of Rapidly Rotating Cast Billets

摘要

In this study, we investigated distribution parameters such as particle size, of both powder and metalpowder composite (MPC) forms of steel 20X23H18 with a fraction of less than 63 microns after plasma melting and centrifugal spraying of a rapidly rotating cast billet using the plasma rotate electrode process method. We have discussed the morphology (appearance) of the MPC particles with a fraction of less than 63 microns. The flowability, angle of repose (looseness), and relative and bulk densities of the MPC were determined, and the yield ratio of the MPC was calculated. The quality of steel grade 20X23H18 MPC with a fraction of less than 63 microns and its application in the manufacture of parts by the method of selective laser sintering are discussed.
