Verfahren zur Herstellung einer Korrosionsschutzschicht für Wärmedämmschichten aus hohlen Aluminiumoxidkugeln und äußerster Glasschicht und Bauteil sowie Materialmischung  Process for the preparation of a corrosion protection layer for thermal insulation layers of hollow aluminum oxide spheres and outermost glass layer and component and material mixture
Die Erfindung betrifft den Schutz einer Wärmedämmschicht gegen Korrosion, die hohle Aluminiumoxidkugeln aufweist und des Weiteren eine glasartige äußerste Schutzschicht aufweisen kann . The invention relates to the protection of a thermal barrier coating against corrosion comprising hollow aluminum oxide spheres and further comprising a glassy outermost protective layer.

teilstabilisiertem Zirkon oder Gadoliniumzirkonat beschichtet werden. Die heutigen Oberflächentemperaturen der Keramiken in Verbindung mit Verunreinigungen wie CMAS führen zu chemischen Angriffen der Keramiken und auch zum Eindringen von partially stabilized zirconium or gadolinium zirconate. Today's surface temperatures of ceramics in combination with impurities such as CMAS lead to chemical attack of the ceramics and also to penetration of
Flüssigphasen in die Poren der Keramik. Gleichzeitig kann der Abrieb von Verdichterabradables zu einmaligen Nickelbelägen auf den Schichten führen. Auch dies führt zu TBC Abplatzungen durch reduzierte Wärmedehnungen. Bisher gibt es kein Liquid phases in the pores of the ceramic. At the same time, the abrasion of Verdichterabradables can lead to unique nickel coatings on the layers. This too leads to TBC flaking due to reduced thermal expansions. So far there is no
langzeitig stabiles System gegen diesen Mehrfachangriff. long-term stable system against this multiple attack.
