Appendix II

X-ray diffraction patterns

In this Appendix the most relevant XRD patterns are reported. The Appendix is

divided into five sections according to the nature of the analysed sample:

Section 1:

Yttria Partially stabilized Zirconia TBCs;

Section 2:

Zirconia co-doped with Yttria and 2mol% Gadolinia TBCs;

Section 3:

Zirconia co-doped with Yttria and 4mol% Gadolinia TBCs;

Section 4:

Zirconia co-doped with Yttria and 1mol% Dysprosia TBCs;

Section 5:

Zirconia co-doped with Yttria and 2mol% Dysprosia TBCs.

Each section is divided into two parts according to the specimen thermal history:

Part 1:

As-deposited TBCs;

Part 2:

Heat-treated TBCs.

Each part is then divided into sub-sections reporting the patterns of powdered

TBCs and of TBCs deposited on different substrates in case more than one

grade of alumina was used. Sometimes more than one TBC texture was found

for the same type of substrate, in this case the different patterns have been

reported.

In the heat treated TBCs section, the title of each pattern reports the ageing

temperature and the total ageing time (in hours); when such time is the result of

more than one ageing cycle, the duration of each cycle is indicated in brackets.

The amount of dopants (Dysprosia and Gadolinia) added to 7YSZ in the different

specimens is always indicated as a molar percentage.

In the next page is reported an index of this Appendix in order to facilitate the

consultation.
