Abstract:
Extensive research is currently done on microstructure and mechanical property characterisation of metal additive manufacturing technologies. However, there remains a limited focus on the combination of these technologies. This study addresses this gap by combining laser powder bed fusion (LPBF) and directed energy deposition (DED) technologies to produce a check valve. The interior of a valve requires high corrosion resistance which can be obtained using In718, while the exterior benefits from more cost effective material, in this case 316L. From the consolidation side, LPBF allows the production of small complex features and DED offers a higher production rate and the possibility of tailoring compositions and mechanical properties. The interface quality and microstructure of different multi-material combinations were studied in this work. Tensile properties were investigated of hybrid multi-material parts to select the best combination. In addition, the production route for producing a multi-material check valve combining LPBF and DED was developed.
