3DPMD-Arc-based additive manufacturing with titanium powder as raw material

摘要

The study aims to demonstrate the suitability of the 3DPMD for the production of titanium components with and without reinforcing particles in layer-by-layer design.Various demonstrators are prepared and analyzed.The microstructure,the porosity and the hardness values of the different structures are compared with each other through metallographic cross-sections.The uniform distribution of the carbides and the interaction with the matrix was analyzed by SEM and EDX.The miller-test method (ASTM G75-07) was used to determine data for the relative abrasivity of the structures.In summary,3DPMD offers the possibility to produce titanium structures with and without reinforced particles.Using automated routines,it is possible to generate metal structures using welding robots directly from the CAD drawings.Microstructures and properties are directly related to the process and therefore material-process-property relationships are discussed within this work.
