Adhesion of Plasma Sprayed Zirconia
Plasma sprayed thermal barrier coatings fail by spalling from components during service. Very little is understood about the ceramic to metal adhesion in the first coating layers. Plasma sprayed coating elements were studied by imaging in electron and optical microscopes. The fragmentation of these thin film elements and their interfacial delamination is studied to determine adhesion strength variations. Novel electron microscopy and fragment statistics have been used in the analysis.
