Current status of thermal barrier coatings — An overview
TL;DR: The state-of-the-art thermal barrier coatings for gas turbine applications are currently a plasma-sprayed ZrO 2 -(6%8%) Y 2 O 3 ceramic layer over an MCrAlY (M ≡ Ni, Co or NiCo) bond coat layer plasma sprayed at low pressure.
Journal ArticleDOI
Failure mechanisms of thermal barrier coatings exposed to elevated temperatures
Robert A. Miller,Carl E. Lowell +1 more
TL;DR: In this paper, the failure of a ZrO2-8%Y2O3/Ni-14% Al-0.1% Zr coating system on Rene 41 in Mach 0.3 burner rig tests was characterized.
Journal ArticleDOI
Oxidation‐Based Model for Thermal Barrier Coating Life
TL;DR: In this paper, a procedure for modeling the lives of thermal barrier coatings subjected to high-temperatrue environments is described, based on the assumption that oxidation is the single important time-dependent factor which limits the life of these coatings, and that oxidation-induced strains combine with cyclic strains to promote slow crack growth in the ceramic layer.
Journal ArticleDOI
Upper Temperature Limit of Environmental Barrier Coatings Based on Mullite and BSAS
Kang N. Lee,Dennis S. Fox,Jeffrey I. Eldridge,Dongming Zhu,Raymond C. Robinson,Narottam P. Bansal,Robert A. Miller +6 more
TL;DR: The state-of-the-art environmental barrier coatings (EBCs) for Si-based ceramics consist of three layers: a silicon bond coat, an intermediate mullite (3Al2O3-2SiO2), and a BSAS top coat as discussed by the authors.
Journal ArticleDOI
Thermal Conductivity and Elastic Modulus Evolution of Thermal Barrier Coatings under High Heat Flux Conditions
Dongming Zhu,Robert A. Miller +1 more
TL;DR: In this paper, a laser high heat flux test approach has been established to obtain critical properties of ceramic thermal barrier coatings (TBCs) under near-realistic temperature and thermal gradients that may be encountered in advanced engine systems.
