摘要： An abrasive coating for a substrate of a component in a gas path exposed to a maximum temperature of 500 degrees Fahrenheit (260°C), comprising: a plurality of grit particles (18) adapted to be placed on a top surface (26) of the substrate (14); a matrix material (20) bonded to the top surface (26); the matrix material (20) partially surrounds the grit particles (18), wherein the grit particles (18) extend above the matrix material (20) relative to the top surface (26); and a film of oxidant resistant coating (28) applied over the plurality of grit particles (18) and the matrix material (20).

摘要： A compressor airfoil (100) has a leading edge (102), a trailing edge (104), and a radially outboard edge (106) connecting the leading edge (102) and the trailing edge (104). The leading edge (102) is formed according to a leading edge tip profile (110) and the trailing edge (104) is formed according to a trailing edge tip profile (112). The leading edge tip profile (110) and/or trailing edge tip profile (112) has a chamfer and/or a radius. In this manner, contact stress experienced by the compressor airfoil (100) such as upon contact with a surrounding abradable seal (122) are ameliorated. The leading edge tip profile (110) and/or trailing edge tip profile (112) are coated with an abrasive coating (108) such as to enhance fitting of the abradable seal (122) to the path of the compressor airfoil (100) upon such contact.
摘要翻译： 压缩机翼（100）具有前缘（102），后缘（104）和连接前缘（102）和后缘（104）的径向外侧边缘（106）。 前缘（102）根据前缘尖端轮廓（110）形成，并且后缘（104）根据后缘尖端轮廓（112）形成。 前缘末端轮廓（110）和/或后缘末端轮廓（112）具有倒角和/或半径。 以这种方式，改进了压缩机翼型件（100）经受的接触应力，例如与周围的可磨损密封件（122）接触时的接触应力。 引导边缘末端轮廓（110）和/或后缘末端轮廓（112）涂覆有研磨涂层（108），以便增强可磨损密封件（122）与压缩机翼型件（100）的路径的接合， 这样的接触。

摘要： A blade outer airseal has a body comprising: an inner diameter (ID) surface; an outer diameter (OD) surface; a leading end; and a trailing end. The airseal body has a metallic substrate and a coating system atop the substrate along at least a portion of the inner diameter surface. At least over a first area of the inner diameter surface, the coating system comprises an abradable layer system comprising a plurality of layers including a relatively erosion-resistant first layer atop a relatively abradable second layer.
