  text: "Friction-spinning is an incremental forming process, which is accompanied
    by complex thermal and mechanical loads in the tool and the formed part. To influence
    the process temperature, two main process parameters, i.e. the rotation speed
    and the feed rate, can be adapted. With the objective to improve the tool performance
    and the quality of the workpiece, this study focuses on a coating concept for
    friction-spinning tools made of high speed steel (HS6 5 2C, 1.3343). On the one
    hand, atmospheric plasma sprayed (APS) Al2O3 and ZrO2-8Y2O3 coatings serve as
    a thermal insulator, and, on the other hand, physically vapor deposited (PVD)
    TiAlSi7.9N and CrAlSi7.5N films are applied to increase the hardness and wear
    resistance of the tools. In addition, duplex coatings, combining the APS and PVD
    technique, are synthesized to influence both the heat transfer and the tribological
    properties of friction-spinning tools.\r\nSubsequently, all coated tools are tested
    in a friction-spinning process to form flanges made of AW-6060 (AlMgSi   3.3206)
    tube materials. The tool temperatures are determined in-situ to investigate the
    impact of the tool coating on the process temperature. Compared to an uncoated
    tool, the alumina and zirconia coatings contribute to a reduction of the tool
    temperature by up to half, while the PVD films increase the hardness of the tool
    by 20 GPa. Furthermore, it is shown that the surface quality of thermally sprayed
    (TS) or PVD coated tools is directly related to the surface roughness of the resulting
    workpiece.\r\n"
