Breviary Technical Ceramics


      Joining and Bonding Techniques

 Bear Thermal Expansion in Mind


  • compensate for
    expansion with
    elastic clamping
    o provide spring washers

o provide spring
jointing elements


o in tapered seats, always keep the ceramic under compression


  • introduce intermediate compliant layers

  • design clearance between parts such that differences in thermal expansion coefficient do not lead to mismatches
    • D > d(STT+1)
      at assembly
