Abstract

Disk-shaped functionally gradient materials of a material combination of partially stabilized zirconia and stainless steel were fabricated by hot pressing. The specimens were evaluated by burner heating test using H2/O2 combustion flame, in which the ceramic surface was heated with burner flame and bottom surface cooled with water flow. The temperature difference given to the sample during the testing generated extensive thermal stress, which caused vertical crack formation at the ceramic surface. The test temperature of the first crack formation was defined as a thermal barrier performance of the tested sample. The composition profile and thickness of the graded layer were varied to study the thermomechanical response. The crack formation temperature was found to be almost constant, being independent of the testing and grading conditions, which indicated intrinsic dependency of the thermal barrier property on material species. The crack formation mechanism was discussed on the basis of a thermal stress analysis using finite element method.
