摘要： A method for forming a textured bond coat surface (48) for a thermal barrier coating system (44) of a gas turbine component (34). The method includes selectively melting portions of a layer of alloy particles (16) with a patterned energy beam (20) to form successive layers of alloy material (16′, 16″) until a desired surface geometric feature (26) is achieved. The energy beam pattern may be indexed between layers to form a protruding undercut (28) in the geometric feature. The patterned energy beam may be formed by directing laser energy from a diode laser (30) through a cartridge filter (32). Particles of a flux material (18) may be melted along with the alloy particles to form a protective layer of slag (22) over the melted and cooling alloy material.

摘要： A wear sensor (30, 50, 60) installed on a surface area (24) of a component (20, 21) subject to wear from an opposing surface (74, 75). The sensor has a proximal portion (32A, 52A, 62A) and a distal portion (32C, 52C, 62C) relative to a wear starting position (26). An electrical circuit (40) measures an electrical characteristic such as resistance of the sensor, which changes with progressive reduction of the sensor from the proximal portion to the distal portion during a widening reduction wear of the surface from the starting position. The measuring circuit quantifies the electrical changes to derive a wear depth based on a known geometry of the wear depth per wear width. In this manner, wear depth may be measured with a surface mounted sensor.

摘要： A structure and method for instrumenting a component for monitoring wear in a coating. The method includes depositing a first thin layer of electrically insulating material, depositing a thin electrically conductive layer over the first electrically insulating layer, depositing a second thin layer of electrically insulating material over the electrically conductive layer. An overlying thickness of the coating material is deposited over the second thin layer of electrically insulating material. The thicknesses of the insulating and conducting layers is controlled to be small enough such that the overlying coating surface exposed to mechanical wear retains a desired degree of smoothness without the necessity for a separate planarization step.

摘要： A method for estimating life of a component includes obtaining fracture data corresponding to a component. The fracture data includes a first dataset corresponding to a threshold region where the crack in the component is dormant below a fatigue threshold. The method further includes determining initial estimates of parameters of a crack growth rate model and parameters of temperature models corresponding to the crack growth rate model based on the fracture data. The method also includes computing optimized parameters of temperature models corresponding to the crack growth rate model, and a scatter parameter via simulation of a joint optimization method using the initial estimates. The method includes determining a cumulative distribution function based on the optimized parameters and the scatter parameter and estimating life of the component based on the cumulative distribution function.

摘要： A system (10) is provided for sealing a gap (12) between a transition exit frame (14) and a vane rail (18) at a turbine inlet (20). The system includes a seal (11) with a compliant seal member having a generally u-shaped profile to provide a sealing function in an axial direction. The compliant seal member includes a U-shaped inner sheet (28) securely pressed within a U-shaped outer sheet (26). The outer and inner sheets include spaced-apart segments (30, 32) in a lateral direction which are spaced-apart by misaligned slots (36, 38) to block passage of air there through. The system may also include wear resistant material (62) interposed between the seal and the vane rail. A lateral gap between adjacent exit frames may include a plurality of ribs defining valleys and tips, with crushable material disposed between the valleys and tips.
