Definitions
- the invention relates to a ceramic layer system, is sprayed in the partially stabilized and fully stabilized powder as physika ⁇ metallic mixture or has been.
- Ceramic thermal barrier coatings For high-temperature applications, such as gas turbines, metallic substrates are often protected by ceramic thermal barrier coatings.
- Typical thermal barrier coatings have zirconia partially stabilized, such as 8 weight percent yttria-stabilized zirconia. Likewise known is fully stabilized zirconium oxide, which then has mostly as a bonding layer teilstabili ⁇ catalyzed zircon layer on the substrate.
- double-layered systems always have the problem of the difference in coefficients of thermal expansion. It is therefore an object of the invention to solve the above-mentioned problem.
- the object is achieved by a ceramic layer system according to claim 1.
- FIGS. 1 to 4 show ceramic thermal barrier coating systems.
- yttrium partially stabilized zirconia PSZ
- FSZ yttria fully stabilized zirconia
- the area specifications for the Sta ⁇ bilmaschine may vary, as can the type of sta- be changed bilisatoren, such. As ytterbium, europium, etc. or mixtures can be used.
- Figure 1 shows an inventive ceramic layer system 1 ⁇ with a substrate 4 of a preferably existing metal ⁇ metallic bonding layer 7, and in particular MCrAlY-Ba-sis, and an outer ceramic thermal barrier coating 10 having a physical mixture of partially stabilized and (fully stabilized zirconia ZrO > 2).
- M is preferably nickel (Ni) and / or cobalt (Co).
- the proportion of FSZ in the mixture or in the TBC is preferably between 10% by weight and 90% by weight.
- Figure 2 shows a similar embodiment of a layer system 1 ⁇ ⁇ , in which, as indicated by the arrow, in the Kerami ⁇ rule layer 10 ⁇ a concentration gradient C is present, so that the proportion of the fully stabilized phase FSZ, for example, outwardly to the outermost surface 19 increases.
- the concentration gradient C can vary over the entire
- Layer thickness of the ceramic layer 10 ⁇ extend or only partially.
- FIG. 3 shows from Figure 1 or 2, the possibility that the substrate 4, 4 ⁇ and / or the adhesive layer 7 an edited structured surface 13 (Engineered surfaces), in order to achieve a better adhesion of the ceramic thermal barrier coating 10, 10 10 ⁇ ⁇ to the substrate 4 ⁇ or adhesive layer 7 ⁇ .
- an edited structured surface 13 Engineerered surfaces
- the structured surface 13 of the substrate 4 ⁇ or the adhesion promoter layer 7 produces an at least 50% greater roughness compared to unprocessed substrates 4 or unprocessed adhesion promoter layers.
- Figure 4 shows an embodiment starting from Figure 1, 2 or 3, in which starting from the outermost surface 19 of the ceramic thermal barrier coating 10, 10 10 ⁇ ⁇ depressions or longitudinal cracks 16 16 ⁇ ⁇ are present, which were preferably introduced later, for. B. by a laser (laser engravings) or by appropriate coating process or subsequent heat treatment process or which were preferably generated during the coating (Dense Vertical Cracks, DVC).
- the substrate 4, 4 ⁇ (Fig. 1, 2, 3, 4) may also be of CMC, in which case the adhesive layer 7 also is preferably ke ⁇ Ramisch.
