“…On the other hand, specimens with TBC, regardless of the production process, show a similar relative temperature trend during the tests (see Figure 6). All temperature profiles were processed, according to Standards [1] and [2], by considering the temperature increment up to the maximum temperature value. Figure 7 shows the normalized relative temperature profile of each test with respect to its maximum value.…”

“…In general, EB-PVD TBCs show a superior durability due to the columnar structure, but they are very expensive compared to APS TBCs. Nowadays, Suspension Plasma Spraying (SPS) technology provides a promising methodology to produce advanced thermal barrier coatings using nanopowders [2]. This process is capable of producing coatings with different types of structure, from very dense and compact ones to columnar with high volume of vertical intercolumnar voids.…”

Aim of this paper is to define and set up an experimental procedure, based on active thermography, for the characterization of thermal barrier coatings for industrial applications, above all in aerospace field. The developed procedure is intended to be a fast and reliable method, alternative to the consolidated one described in International Standards as ISO18755 and ISO18555. In particular, this approach consists of a pulsed active thermography, in transmission configuration, obtained by means of a laser excitation. Temperature data processing, according to and adapting Standard procedures, allowed us to determine thermal parameters as conductivity and diffusivity. Obtained results were compared in terms of thermal properties variation with respect to base and coated materials, and in term of different coating procedures. These results were also compared to those available in literature.

Characterization of Thermal Barrier Coatings Using an Active Thermography Approach

et al. 2022

The aim of this paper is to define and set up an experimental procedure, based on active thermography, for the characterization of coatings for industrial applications. This procedure is intended to be a fast and reliable method, alternative to the consolidated one described in International Standards. In more detail, a classical active thermographic set up, and not a dedicated apparatus, was used for that aim, and data processing techniques referred to the analytical approach described in Standards. The active thermography procedure provided the measurement of the surface temperature of specimens undergoing a thermal excitation, applied by means of a laser pulse (Pulsed Technique). Temperature data processing, according to and adapting the Standard procedures, allowed to obtain thermal conductivity and diffusivity information. In particular, two coating processes (Atmospheric and Suspension Plasma Spray) applied to the same base material, Inconel 601, and the same coating material were investigated. These results were compared in terms of thermal properties variation with respect to base and coated materials, and in terms of different coating processes (APS and SPS). Obtained results were also compared to those available in literature.
