   Nyckelord :thermal barrier coatings; TBC; small punch test; miniaturised disc bending test; mdbt; spherical indentation; gas turbine coatings; NiAl; NiCoCrAlY; NiCrAlY; mechanical properties;

   Sammanfattning : Coatings are frequently applied on gas turbine components inorder to restrict surface degradation such as corrosion andoxidation of the structural material or to thermally insulatethe structural material against the hot environment, therebyincreasing the efficiency of the turbine. However, in order toobtain accurate lifetime expectancies and performance of thecoatings system it is necessary to have a reliableunderstanding of the mechanical properties and failuremechanisms of the coatings.

4. 3. Thermal Barrier Coatings : Durability Assessment and Life Prediction

   Författare :Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER

5. 4. Aspects of fatigue life in thermal barrier coatings

   Författare :Håkan Brodin; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Thermal barrier coatings (TBC) are applied on hot components in airborne and land-based gas turbines when higher turbine inlet temperature, meaning better thermal efficiency, is desired. The TBC is mainly applied to protect underlying material from high temperatures, but also serves as a protection from the aggressive corrosive environment. LÄS MER
