Ashley and Greg performed summer research at Boeing Seattle
We are pleased to announce that our paper titled “Detrimental effects of sand ingression in jet engine ceramic coatings captured with Raman-based 3D rendering”, by lab member Zachary Stein, has been published in the Journal of the European Ceramic Society. The work presented in this paper was done in collaboration with the German Aerospace Center (DLR) through the NSF International Research Experience for Students (IRES) program. The results were obtained using 3D confocal Raman spectroscopy to map the thermochemical evolution of monoclinic phase volume fraction in standard EB-PVD TBC coatings infiltrated with CMAS. This provided a method for quantitatively and non-destructively characterizing the degradation of coatings as a result of CMAS infiltration.
