| Abstract Scope |
Thermal barrier coatings typically fail on cooling after prolonged thermal cycling by the growth of sub-critical interface separations. Observations of coating cross-sections together with measurements of stress re-distribution obtained through the thickness of intact coatings using piezospectroscopy reveal how small, isolated regions of damage form, grow and link up to form a percolating interface fracture. These observations will be described and used to develop a model for damage evolution on thermal cycling. |
