abstract = {In three different examples, the effects of the oxidation
behaviour as well as the microstructural stability of high
temperature materials and protective coatings was determined
by combining the results of kinetic studies with extensive
analytical investigations using, among other techniques,
SNMS, SIMS, SEM, TEM, Rutherford back scattering (RBS) as
well as X-ray diffraction. 1). The effect of water vapour on
the oxidation behaviour of $9\%$ Cr steels in simulated
combustion gases has been determined. The effects of O2 and
H2O content on the oxidation behaviour of $9\%$ Cr steel in
the temperature range 600-800 degrees C showed that in dry
oxygen a protective scale was formed with an oxidation rate
controlled by diffusion in the protective scale. In the
presence of water vapour, after an incubation period, the
scales became non-protective as a result of a change in the
oxidation limiting process. The destruction of the
protective scale by water vapour does not only depend on H2O
content but also on the H2O/O2-ratio. 2). The increase of
component surface temperature in modern gas turbines leads
to an enhanced oxidation attack of the blade coating.
Improvements in corrosion resistance and longer lifetime
thermal barrier coatings in gas turbines have been achieved
by improvement of the high temperature properties of MCrAlY
coatings by additions of minor alloying elements such as
yttrium, silicon and titanium. 3). The use of oxide
dispersion strengthened (ODS) alloys provides excellent
creep resistance up to much higher temperatures than can be
achieved with conventional wrought or cast alloys in
combination with suitable high temperature
oxidation/corrosion resistance. Investigation of the growth
mechanisms of protective chromia and alumina scales were
examined by a two-stage oxidation method with 18O tracer.
The distribution of the oxygen isotopes in the oxide scale
was determined by SIMS and SNMS. The results show the
positive influence of a Y2O3 dispersion on the oxidation
resistance of the ODS alloys and its effect on growth
mechanisms.},
