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.

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.}, language = {en} } @article{HartmannKnoppShandyetal., author = {Hartmann, J{\"u}rgen and Knopp, Kevin and Shandy, Amir and Winterstein, Achim and Arduini, Mariacarla and Hemberger, Frank and Vidi, Stephan and Manara, Jochen and M{\"u}ller, Michael}, title = {Thermophysikalische Charakterisierung von W{\"a}rmed{\"a}mmschichten}, series = {tm - Technisches Messen}, volume = {88}, journal = {tm - Technisches Messen}, number = {12}, publisher = {Oldenbourg Wissenschaftsverlag}, doi = {10.1515/teme-2021-0074}, abstract = {Die Effizienzsteigerung moderner Gasturbinen erfordert die stetige Anhebung der Betriebstemperatur.
