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 ceramic thermal barrier coating (TBC) (18) having first and second layers (20, 22), the second layer (22) having a lower thermal conductivity than the first layer for a given density. The second layer may be formed of a material with anisotropic crystal lattice structure. Voids (24) in at least the first layer (20) make the first layer less dense than the second layer. Grooves (28) are formed in the TBC (18) for thermal strain relief. The grooves may align with fluid streamlines over the TBC. Multiple layers (84, 86, 88) may have respective sets of grooves (90), Preferred failure planes parallel to the coating surface (30) may be formed at different depths (A1, A2, A3) in the thickness of the TBC to stimulate generation of a fresh surface when a portion of the coating fails by spalling. A dense top layer (92) may provide environmental and erosion resistance.
