Production of MMCs on the Basis of Fibres Coated with the Metal Alloy by Magnetron Sputtering

Thermal fatigue damage in monofilament reinforced copper for heat sink applications in divertor elements

“…Pure Cu as well as CuCrZr (Cr $ 0.7 wt.%; Zr $ 0.1 wt.%) matrices were tested [6][7][8][9][10]. The MFRM samples were produced by Deutsches Zentrum für Luft-und Raumfahrt (DLR) and some by Max Planck Institute (IPP) in cooperation with European Aeronautic Defence and Space Company (EADS) [7,12]. First step in production is the fiber coating with an interlayer followed by Cu or CuCrZr matrix material deposition by magnetron sputtering or galvanic Cu coating in thickness dependent on the required volume fraction.…”
