摘要：

Processing and characterization of ceramic coatings for thermal barrier applications Electrochemical impedance spectroscopy is being developed as a non-destructive evaluation technique for life-remain assessment and quality control of thermal barrier coatings. In this investigation, changes in electric properties of coatings deposited by thermal spray were measured by electrochemical impedance spectroscopy as a function of the isothermal oxidation in air at different times. Finally, the results obtained by electrochemical impedance spectroscopy were related to the coating's microstructure studied by environmental scanning electronic microscopy and energy-dispersive X-ray microanalysis.
