Abstract: Thermal barrier coatings (TBCs) for turbine engine components are applied over engineered surface features (ESFs) that are formed in the component substrate or within intermediate layers applied between the substrate and the TBC. The ESFs help anchor the TBC layer and/or localize cracks that are bounded by one or more of the ESFs. During engine operation the ESFs arrest thermal stress- or foreign object damage (FOD)-induced crack propagation within the TBC that might otherwise allow excessive TBC spallation and subsequent thermal exposure damage to the turbine component underlying substrate. In some embodiments, the ESFs are combined with engineered groove features that are formed in the TBC.

Abstract: The present invention relates to a seal system for gas turbine, the seal comprising a stator (4) and a blade (3) with a blade tip (25) facing the stator (4). The blade comprises a protective ceramic coating (21) having an inner ceramic layer (19) being made of a partially stabilized zirconia and having at least a partially segmented microstructure in form of vertical cracks. The ceramic coating (21) further comprises an outer ceramic layer made of fully stabilized zirconia and having a segmented microstructure. Preferably, the entire airfoil surface is provided with the protective ceramic coating (21). With the fully stabilized zirconia coating on tip (25) of a blade which faces a casing with a ceramic coating (16) would results in a better sealing system. The stator (4) comprises an abradable coating (15) having at least an outer ceramic coating being made of fully stabilized or ytterbium stabilized zirconia.

Abstract: A turbine abradable component includes a support surface and a thermally sprayed ceramic/metallic abradable substrate coupled to the support surface for orientation proximal a rotating turbine blade tip circumferential swept path. An elongated pixelated major planform pattern (PMPP) of a plurality of discontinuous micro surface features (MSF) project from the substrate surface. The PMPP repeats radially along the swept path in the blade tip rotational direction, for selectively directing airflow between the blade tip and the substrate surface. Each MSF is defined by a pair of first opposed lateral walls defining a width, length and height that occupy a volume envelope of 1-12 cubic millimeters. The PMPP arrays of MSFs provide airflow control of hot gasses in the gap between the abradable surface and the blade tip with smaller potential rubbing surface area than solid projecting ribs with similar planform profiles.
