Abstract: Coatings containing at least 85 % by volume crystalline mullite with less than 15 % by volume of amorphous material and mullite dissociation phases are plasma sprayed onto the surface of a silicon based ceramic substrate by closely controlling the plasma spray parameters including the mullite feed stock and its particle size, the nozzle outlet stand-off distance, movement of the substrate past the plasma flow, back side heating of the substrate and the powder feed rate through the plasma spray gun.

Abstract: A segmented abradable ceramic coating system having superior abradability and erosion resistance is disclosed. The system includes a duct segment having a metallic substrate 12, a MCrA1Y bond coat 14 on the substrate and a segmented abradable ceramic coating 16 on the bond coat. The segmented abradable ceramic coating includes a base coat foundation layer 18, a graded interlayer 20 and an abradable top layer 22 for an overall thickness of preferably about 50 mils (1.270 mm). The coating is characterized by a plurality of vertical microcracks. By precisely controlling the deposition parameters, composition of the layers and layer particle morphology, segmentation is achieved, as well as superior abradability and erosion resistance.
