The aim of this study was to investigate the tribological behaviour of laser cladded aluminum bronze tool\nsurfaces for dry metal forming. In a first part of this work a process window for cladding aluminum bronze on steel\nsubstrate was investigated to ensure a low dilution. Therefore, the cladding speed, the powder feed rate, the laser\npower and the distance between the process head and the substrate were varied. The target of the second part was\nto investigate the influence of different process parameters on the tribological behaviour of the cladded tracks. The\nlaser claddings were carried out on both aluminum bronze and cold work tool steel as substrate materials. Two different\nparticle sizes of the cladding powder material were used. The cladding speed was varied and a post-processing\nlaser remelting treatment was applied. It is shown that the tribological behaviour of the surface in a dry oscillating\nball-on-plate test is highly dependent on the substrate material. In the third part a deep drawing tool was additively\nmanufactured by direct laser deposition. Furthermore, the tool was applied to form circular cups with and without\nlubrication.
