  • Joining of C_f/SiC Ceramics to Nimonic Alloys
    Journal of Materials Engineering and Performance, 2012
    Co-Authors: C. Jimenez, N. V. Moutis, X. Azpiroz, Christian Wilhelmi, K Mergia, Th. Speliotis, S. Messoloras
    Abstract:

    C_f/SiC ceramic composites have been brazed to Nimonic Alloys using TiCuAg filler metal. In order to improve wettability and to provide compatibility between ceramic and metal, the C_f/SiC surface was metallized through the deposition of a chromium layer. Subsequent heat treatments were carried out to develop intermediate layers of chromium carbides. Excellent wetting of both the composite ceramic and the metal from the filler metal is observed in the fabricated joints. Shear tests show that failure occurs always within the ceramic material and not at the joint. In the filler region depletion of Ti and formation of Ag and Cu rich regions are observed. At the C_f/SiC-filler interface a layered structure of the filler metallic elements is observed. Titanium interacts with the SiC matrix to form carbides and silicides.

  • brazing of carbon carbon composites to Nimonic Alloys
    Journal of Materials Science, 2010
    Co-Authors: N. V. Moutis, X. Azpiroz, S. Messoloras, Christian Wilhelmi, Th. Speliotis, C. Jimenez, K Mergia
    Abstract:

    Industrially produced Cf/C ceramic composites have been brazed to Nimonic Alloys using a TiCuSil filler metal. Ιn order to accommodate the different linear coefficients of expansion between ceramic and metal as well as to provide compatibility between the surfaces to be joined, the Cf/C surface was metallized through the deposition of a chromium layer. Subsequent heat treatments were carried out to develop intermediate layers of chromium carbides. Crack-free joints have been produced and shear tests show that failure occurs within the composite. At the Cf/C-filler interface a layered structure of the metallic elements is observed. Titanium is depleted from the filler zone and interacts with the carbon to form carbides. In the filler region, Ag and Cu rich regions are formed.
