Non-destructive evaluation (NDE) is a term often used together with NDT. However, NDE is used to describe measurements that are more quantitative in nature, i.e. detection of the defect is not enough, quantitative information is required regarding flaw size, shape and orientation, information which could be used to determine the component s suitability for use. 

Non-Destructive Techniques. There is a wide range of different variants of non-destructive evaluation (NDE), non-destructive testing (NOT) and nondestructive inspection (NDI) techniques in order to identify local damage and the onset of damage in critical structures. In particular, ultrasonic inspections used over several decades are still most popular [102].

Many characterization techniques require destruction or signification modification of the sample. In some cases, evaluations can be made by non-destructive evaluation (NDE) and then used. Examples include four-point probe resistivity measurements, adhesion (tensile pull to value), thermal transmission, and RBS analysis. 

Since the resistance of the TGO is proportional to its thickness, the TGO growth with isothermal or thermal cycling can be non-destructively evaluated from the impedance spectra [97-99]. Indeed, any small change in electrical properties induced by the phase transformation can be detected by the impedance measurement due to its high sensitivity. For example, the monoclinic phase has a different conductivity than t phase, as a result, the t-m transformation of the YSZ can be monitored by impedance spectra [97]. In addition, this technique has the potential to detect microstructural evolutions, such as TBC sintering, interfacial cracks and spinel formation at the interface, wfrich make it as a promising technique for NDE of TBCs.
