Zusammenfassung:	SE DESCRIBE UN SISTEMA DE REVESTIMIENTO CERAMICO DESGASTABLE SEGMENTADO QUE TIENE RESISTENCIA SUPERIOR AL DESGASTE Y A LA EROSION. EL SISTEMA INCLUYE UN SEGMENTO DE CONDUCTO QUE TIENE UN SUSTRATO METALICO 12, UNA CAPA DE UNION MCRA1Y 14 EN EL SUSTRATO Y UN REVESTIMIENTO CERAMICO DESGASTABLE SEGMENTADO 16 EN LA CAPA DE UNION. EL REVESTIMIENTO CERAMICO DESGASTABLE SEGMENTADO INCLUYE UNA CAPA DE ESTABLECIMIENTO DE CAPA DE UNION 18, UNA CAPA INTERMEDIA APLANADA 20 Y UNA CAPA SUPERIOR DESGASTABLE 22 PARA UN GROSOR TOTAL DE PREFERIBLEMENTE ALREDEDOR DE 50 MILESIMAS (1,270 MM). EL REVESTIMIENTO SE CARACTERIZA POR UNA PLURALIDAD DE MICROFISURAS VERTICALES. CONTROLANDO EXACTAMENTE LOS PARAMETROS DE DEPOSICION, SE LOGRA LA COMPOSICION DE LAS CAPAS Y LA MORFOLOGIA DE PARTICULA DE CAPA, LA SEGMENTACION, ASI COMO UNA RESISTENCIA SUPERIOR AL GASTADO Y A LA EROSION. 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.
