New slurry-sintered TBC system
incorporating an electrosynthesized
ceria interlayer.
Growth mechanisms and intermetallic
formation elucidated by SEM/
EDS, 3D-DSC and TGA.
Selective diffusion barrier ability of
ceria demonstrated to limit Cr upward
diffusion.
Thicker b-NiAl coating obtained by
delayed Al diffusion and enhanced Ni
outward diffusion.
Thicker crusts of alumina spheres
and greater sintering of the Al2O3
shells evidenced with ceria.
