Abstract

Stress mapping in a thermally grown oxide (TGO) was carried out using a near field optical microscope. The local stress distribution in a TGO layer of a thermal barrier coating system after thermal exposure was measured. Results demonstrated that the stress in the TGO layer was non-uniform, and the lowest compressive stresses in the TGO layer were found to be close to the bond-coat.
