Modification of metals for additive manufacturing using RF-plasmaTuesday (27.09.2016) 15:30 - 15:45 Part of:
The raising interest in additive manufacturing technologies (AMT) has also brought the need to modify and adapt also established materials to these rather new technologies. An extensive commercialization of products made by AMTs like Selective Laser Melting (SLM) requires further improved metal and ceramic powder particles as starting materials and a controlled quality of such powder particles concerning their shape, size distribution and surface. The quality and the homogeneity of the powder particles as starting materials are related to the efficiency of the manufacturing process and the quality of the made workpiece.
One material, where further modification and homogenization for SLM is necessary, is titanium. Modification of titanium for SLM is of special interest due to the use in lightweight and biomedical applications. A method to modify it for the use in SLM is Radio Frequency (RF)-plasma. Tasks to achieve homogenized powders using RF-plasma from will be discussed from the production technology point of view.
