Definitions
- the invention relates to a thermal insulation for a component within the hot gas region of a gas turbine having the features of the preamble of claim 1.
- the surfaces in the hot gas area are almost completely provided with coatings in modern gas turbines. Exceptions are in some cases still the blades of rear turbine rows.
- the thermal insulation layers serve to lower the
- Zirconium oxide which is generally partially stabilized with about 7% by weight of yttrium oxide (International abbreviation: "YPSZ” by Yttria Partially Sitabilized Zircoma), has become established as the ceramic material for the thermal insulation layer m are divided into two main classes: - Thermally sprayed layers (usually with atmospheric pissma, APS), in which, depending on the desired layer thickness and stress distribution, a porosity between approximately 10 and 25% by volume m of the ceramic layer is set to ( ⁇ Au ⁇ resp ⁇ L: th * ⁇ haftscnj.cht done by rpecnar .. see Ver'zlamm réelle - lij-creLs ⁇ lektronenstrahl deposited £ 3. Sc ⁇ icfiten
- the DBX compliance with certain deposition conditions comprise a columnar or ko] umnare ⁇ ehnungstolerante structure.
- the layer is chemically bound by formation of an Al / Zr mixed oxide on a pure aluminum oxide layer (TGO) formed by the adhesion layer during the deposition and then in operation, which places particular demands on the oxide growth on the adhesion layer.
- TGO pure aluminum oxide layer

- the praktiscn realizable Al content aass
- the structure of an aluminized MCrAlY layer consists of the inner, largely unchanged ⁇ , ß mixed phase, a diffusion zone in which the Al content increases to ⁇ 20% and an outer ß-NiAl phase in a proportion of about 30% Al ,
- the NiAl phase is the weak point of the coating system in terms of resistance and crack sensitivity.
- the (inter-) diffusion phenomena between the base material and the MCrAlY layer - in the special case also between the MCrAlY layer and the alitization - become lifetime-determining with increasing application temperature.
- the diffusion-induced loss of the oxidation-active aluminum in the MCrAlY layer may exceed the oxide-induced loss.
- the invention is based on the object of avoiding the disadvantages described above and of slowing down the diffusion in a generic protective layer without the oxidation properties of the aluminized layer as well as the bu ) ' LiIir ⁇ r and jstems.-i? ga ⁇ r öeei nfiusst ground ⁇ es SC ic'i c?.
- the diffusion is slowed down by the addition of preferably Re, but also by W, Si, Hf and / or Ta m of the specified concentration by the modification of the particularly composed NiCoCrAlY adhesive layer.
- the service life of the thermal insulation layer, especially the layer applied by EB-PVD is considerably prolonged by the diffusion resistance to the base material and the overbalancing hm. In case of premature failure of the thermal barrier coating, e.g. B. by Fremdkorperem Kunststoff or erosion, a longer "emergency operation" is possible.
- the production of the thermal barrier layer takes place in the following manner.
- an adhesive layer for. B. by thermal spraying applied.
- a prealloyed ⁇ nd dusted powder is used, which has the following chemical composition: Co 15 to 30 wt.%, Cr 15 to 25 wt.%, Al 6 to 13 wt.%, Y 0.2 Dis 0.7 wt.% , Rest Ni.
- the powder contains one or more of the elements Re up to 5 wt.%, ⁇ up to 5 wt.%, Si up to 3 wt.%, Hf Dis 3 wt.%, Ta to 5%.
- the powder used following chemical Zusammer.se " ⁇ ur> g ⁇ Co 25 Ge / 7%, Cr has 21 wt.%, Al 8 wt.%, Y 0.5 wt.% Re 1.5 wt. %, Remainder Ni
- the adhesive layer has the chemical composition of the powder used.
- the overlapping is carried out by means of overalignment, that is to say by a treatment in which a reactive Al-containing gas, as a rule, is added to the surface of the aliquot of Al-Diffusior-Sschj cnt is an Ai-halo ⁇ emd (AlX 2 ), is at a higher temperature Eimvarcs ⁇ iffusion of Al, combined with a Ausvarts ⁇ iffusion of Ni, causes:.
- an inner diffusion zone is formed on the largely unchanged adhesive layer within the diffusion layer, and above this an outer structure of a brittle ⁇ -NiAl phase.
- the outer building layer is removed by blasting with hard particles, such as corundum, silicon carbide, metal wires or other known grinding or polishing down to the inner diffusion zone of the diffusion layer.
- the abrasive treatment is driven so far that the surface of the remaining diffusion layer has an Al content of more than 18% and less than 30%.
- the ceramic layer of zirconia partially stabilized by yttrium oxide is applied by one of the methods mentioned at the outset.
