Definitions

  • the turbine inlet temperature of about 1230 0 C to about 1350 0 C is necessary.
  • This goal can be achieved by using ceramic thermal barrier coatings in addition to the use of improved base materials and effective cooling methods.
  • the permissible surface temperature can be increased by a few 100 K by the thermal insulating effect of the ceramic thermal barrier layer while maintaining the same cooling conditions depending on the thickness of the thermal barrier coating.
  • the greater thermal load often leads to a shortened life of the thermal layer system.
  • thermal conductivity of thermal barrier coatings can be achieved by using ceramic materials with a correspondingly small intrinsic
  • Thermal conductivity can be reliably achieved.
  • thermal barrier coatings in the form of duplex structures are used.
  • the first layer consists of a metallic layer, which has the task of protecting the underlying substrate (component) from corrosion and oxidation.
  • this layer usually serves as a primer layer for the actual thermal barrier coating, as the second layer of the duplex structure.
  • This second layer which performs the actual function of thermal insulation, is often a ceramic layer.
  • These typically consist of yttria-stabilized zirconia (YSZ) or other oxide ceramics.
  • YSZ yttria-stabilized zirconia
  • Newer thermal barrier coating systems sometimes also have multilayer coating systems of various ceramics.
  • suspension solution evaporates abruptly and the small solid particles are aggregated into partially or completely molten droplets, accelerated and impacted on the substrate in order to form a layer there.
  • the suspension plasma spraying can be used for coatings of both ceramic and metallic materials, wherein in each case very fine, dense spherical particles are used.
  • thermal barrier coatings are determined by the thermal conductivity of the material of the thermal barrier coating and by the layer thickness. Under the insulating effect of thermal barrier coatings is understood here the temperature drop across the thermal barrier coating. The layer thickness is limited due to mechanical properties to be fulfilled and can not be made arbitrarily large. These two parameters represent a principal barrier for all thermal barrier coating systems.
  • the APS layer can be used in particular as a mechanically and erosively stable layer and the SPS layer in particular for improving the reflectivity and reducing the thermal conductivity.
  • the advantages of the individual layers can be optimally combined, thus enabling applications that can not be fulfilled by the single-layer systems.
  • the solids content of the powder in the suspension was 10% by weight (Example 1) and 20% by weight (Example 2).
  • the suspension pressure was 2 bar and was operated at an air pressure of 0.5 bar.
  • the layer thickness of the SPS layer was varied between 60 and 150 ⁇ m.
  • the thermal conductivity of this layer was only 0.58 W / mK, the layer having a porosity of about 29%.
  • FIGS. 4a to 4c Shown in FIGS. 4a to 4c are photographs of the layer systems according to the invention.
  • the microstructures in the transverse section of the two double layers are shown in FIGS. 4a and 4b.
  • the layer thickness of the SPS layer is 60 or 150 ⁇ m and for the APS layer 270 or 200 ⁇ m.
  • the SPS layer is interspersed with significantly finer pores and cracks are visible, which in particular pass vertically through the layer. Within the APS layer significantly coarser pores are represented.

Abstract

La présente invention concerne un procédé de fabrication d'un système de couches sur un composant. Selon le procédé, au moins au moins une couche est déposée sur le composant par pulvérisation plasma atmosphérique (APS) et au moins une autre couche est déposée sur le composant par pulvérisation plasma en suspension (SPS). De manière avantageuse, on dépose en particulier les couches dans l'ordre suivant APS + SPS ou APS + SPS + APS ou également APS + SPS + couche d'érosion. Ces séries de couches ainsi appliquées ont ordinairement pour effet la création d'une première couche poreuse ainsi que d'une seconde couche poreuse disposée sur la première, la porosité et la réflectivité de la seconde couche étant supérieures à celle de la première couche. L'augmentation de la réflectivité de la couche, en particulier dans la gamme de longueurs d'ondes d'infrarouges visibles (VIS) et proches (NIR), produit de manière avantageuse une contrainte thermique plus faible du matériau de substrat, étant donné que seule une part plus faible de rayonnement thermique pénètre à travers la couche calorifuge céramique et entraîne ainsi un réchauffement moindre du substrat (composant).
