Fertigung funktional gradierter Materialien auf porösen Metallen durch Laserauftragschweißen

Abstract Novel hybrid porous materials enable the local variation of component properties to meet individual application requirements. To realize complex component geometries, laser directed energy deposition can be used as an additive manufacturing process to produce multifunctional high-performance components made of hybrid porous materials. This work presents results from the manufacturing of functionally graded materials from the stainless steels 316 L (austenitic) and 17-4 PH (martensitic) for this purpose. A grading strategy with a 50 % 316 L and 50 % 17-4 PH interlayer was successfully manufactured and characterized in terms of relative density and microhardness.
