abstract = {Double layer thermal barrier coatings (TBCs) consisting of
a Gd2Zr2O7 (GZO) top and an ytrria stabilized zirconia (YSZ)
interlayer have been tested in a burner rig facility and the
results compared to the ones of conventional YSZ single
layers. In order to gain insight in the high temperature
capability of the alternative TBC material, high surface
temperatures of up to 1550 °C have been chosen while
keeping the bond coat temperature similar. It turned out
that the performance of all systems is largely depending on
the microstructure of the coatings especially reduced
porosity levels of GZO being detrimental. In addition, it
was more difficult in GZO than in YSZ coatings to obtain
highly porous and still properly bonded microstructures.
Another finding was the reduced lifetime with increasing
surface temperatures, the amount of reduction is depending
on the investigated system. The reasons for this behavior
are analyzed and discussed in detail.},
