Abstract

This project focuses on the development of a Multi-User Platform for obtaining Powders through Ultrasonic Atomization and 3D Printing of Titanium Alloys, Light Alloys such as Al and Mg base, multi-main, special and refractory metal alloys for biomedical and advanced applications. Many research groups have focused nowadays on research into metallic materials involving laser additive manufacturing, such as the laser powder bed fusion (LPBF) process, in the production of parts with complex geometries and difficult to process using traditional manufacturing techniques. Brazil and the state of São Paulo have gas atomizers, as at IPT - SP, and DEMa/UFSCar for the production of metallic powders in the order of 5 to 25 kg of alloys, but they do not yet have ultrasonic atomization equipment that allows the production of high-melting alloy powders, reactive (Ti and Mg) or on a small scale, in the range of hundreds of grams (100 to 500 g). The objective of this multi-user project (EMU) is to provide the state of SP and Brazil with a platform for obtaining laboratory-scale metal powders of up to 500 g for ultrasonic atomization of metal alloys (and subsequent processing through laser powder bed fusion (LPBF) with high melting point and special ones, such as Titanium alloys, multi-main alloys (ccc, cfc and hcp) and reactive or refractory alloys in general, which are not capable of being obtained in conventional gas atomizers. The project has the support from partner teams from Spain (Universidad de Sevilla), Czech Republic (Charles University of Prague), Colombia (Universidad de Córdoba) and Brazil in the state of São Paulo (UNICAMP, UNESP, EESC-USP) and other UFC states (Ceará , CE), UFMG (Belo Horizonte - MG) that combine a deep knowledge of the research topic and the possession of advanced experimental techniques for characterizing the metallic alloys of interest to this project, being inherently multi-user.
