Document Type and Number:
Japanese Patent JP4004577
Kind Code:
B2
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.
