Samenvatting

Over the past decades, Inconel 718 and titanium 6Al4V have established their roles as prefered material in the gas turbine industry. Production of complex parts with these alloys using conventional production however is time consuming and expensive. With AM fabrication of metals developing fast, the possibilities for application in the repair or production of gas turbine parts grow. The aim of this research is to prove the capability of laser cladding, selective laser melting, and wire feed electron beam welding as suitable alternatives to conventional production using wrought material. All three methods show promising results, proving capable of producing material with minimum or near minimum material properties. Laser cladding and wire feed electron beam welding achieve good values in Inconel 718, whereas selective laser melting produces good values in titanium 6Al4V, indicating process experience to be a major factor. Defects and porosity are found in some samples, showing the neccessity of optimalization and quality control. KLM and the NLR are recommended to commit to further research, as well as to keep exchanging information on quality and material properties
