Additionally, modern additive manufacturing methods, in particular the 3D metal laser printer requires a detailed control of the melting temperature. Many applications are based on a layered structures, e.g. thermal barrier coatings in gas turbines. Also components manufactured by additive manufacturing pose a layered structure. In these structures the mechanical contact between the layers and to the substrate is of high interest. Besides, the complete characterisation of the additive manufactured component is important for its later application.

Also advanced material processing like 3D laser printing of metals and ceramics are based on a layer-to-layer process at high temperatures, resulting in non-homogeneous components. Both systems require more and more detailed investigation methods to characterise the material properties of the resulting structures and to optimize the relevant processes. To address the required needs in advanced material characterisation recently an attempt was started to develop a unique measurement set-up for advanced material characterisation. This method is based on the well know laser flash principle, which was improved by adding supplementary heating sources and additional detection channels. Combining different heating mechanism and heating times with the two-dimensional measuring of the thermal flow across the sample enables the determination of different opto-thermal parameters and other material properties, e.g. mechanical contact, electrical conductivity or optical data, which also depend on or affect the flow of heat. In this paper we describe the implementation of the different optical methods to measure the thermal heat flow by point-like and two-dimensional temperature measurement and present first results on several samples.

Die derzeitigen Brenngastemperaturen liegen mit über 1400 °C signifikant über der kritischen Temperatur der verwendeten Turbinenstähle. Zur Gewährleistung der Betriebssicherheit werden die Turbinenschaufeln neben Aktivkühlung durch Beschichtung mit thermischen Schutzschichten, sogenannten thermal barrier coatings (TBC), geschützt. Da es sich bei den TBC um Keramikschichten handelt, ist für die Erhöhung der Haftfestigkeit das Aufbringen eines Haftvermittlers (Verbindungsschicht) notwendig. Da die Eigenschaften dünner Schichten stark von den Eigenschaften des Bulkmaterials abweichen können und zudem von der Herstellungsmethode beeinflusst werden, ist eine Untersuchung der thermischen und infrarot-optischen Eigenschaften der tatsächlichen Schichtstrukturen unumgänglich, insbesondere im Hochtemperaturbereich. Hierfür wurden Proben des reinen Trägerstahls, des Trägerstahls mit Haftvermittlerschicht und des kompletten Schichtsystems aus Trägerstahl, Haftvermittlerschicht und Wärmedämmschicht verschiedener Dicken hergestellt und mittels Laser-Flash-Methode untersucht. Die Auswertung erfolgte dabei analytisch, ausgehend von der Trägerstahl-Einschichtprobe, über die Zweischicht- und Dreischichtsysteme. Vervollständigt wurden diese Untersuchungen durch infrarot-optische Charakterisierungen, mit denen sich die Wärmeausbreitung durch die Schichtsysteme beschreiben lässt. Zusammen mit den Laser-Flash Messungen erlaubt dies eine spätere Quantifizierung der einzelnen, bei Keramiken auftretenden, Wärmetransportmechanismen. N2 - Increasing the efficiency of modern gas turbines requires the increase of operating temperature. Current fuel gas temperatures above 1400 °C significantly exceed critical temperatures of the turbine steels used. To ensure operational safety, the turbine blades are actively cooled and also protected by protective layers, the so-called thermal barrier coatings (TBC). Since the TBC are ceramic layers, an adhesion promoter (bond coat) must be applied to increase the adhesive strength. Since properties of thin layers can differ from properties of the bulk material and are also influenced by the manufacturing method, an investigation of the thermal and infrared-optical properties of the actual layer is essential, especially in the high temperature range. For this purpose, samples of the pure carrier steel, the carrier steel with bond coat and the complete layer system of carrier steel, bond coat and TBC of various thicknesses were produced and examined using the laser flash method. The evaluation was carried out analytically, starting from the single-layer sample, via the two-layer and three-layer systems. These investigations were completed by infrared-optical characterizations, allowing the description of the heat transport through the layer systems. These measurements allow a future quantification of the individual heat transport mechanisms occurring in ceramics.
