U02 - Laser Deep Alloying for the Realization of Finely Graded Alloys
laser-based alloying process, by which many reproducible alloys can be produced in fine graduation of their chemical composition. In a first process step, alloy elements are pre-deposited on the base material [...] applications. In laser alloying, the high power density of the focused laser beam is used to melt the base material and alloy elements, thus enabling metal bonding. In subproject U02 micro-samples of different [...] using selective laser beam melting (LBM). In the following step, the alloys are produced by laser-based remelting and mixing of the alloy element layers with the substrate using a scanner-guided laser deep
