Abstract:
In this study it is proposed to use machining metal chips with a pre-established and controlled chemical composition as raw material for metal powder production. The centrifugal atomization technology is used to produce this metal powder, bridging the gap between collecting recyclable metal scraps and obtaining the final powder, therefore enhancing the overall sustainability of the process. This study involves the collection of metal chips, their treatment for the removal of cooling liquids and other residues, and their subsequent use as raw material for metal powder manufacturing. Three different case studies are presented, including AlSi7Mg aluminium alloy, a Sn-based alloy also called White Metal alloy or Babbitt alloy, and a Ti6Al4V titanium alloy, illustrating the versatility and applicability of the proposed approach.
