    Abstract: 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.

    Abstract: A bimetallic bond layer (26, 28) for a thermal barrier coating or TBC (30) on a superalloy substrate (22) for a high temperature environment. An interlayer (26) is applied on the substrate. A bond coat (28) comprising a CoNiCrAlY or NiCoCrAlY alloy is applied on the interlayer. A ceramic TBC (30) such as 8YSZ is applied on the bond coat. The interlayer (26) is an alloy that is compatible with the substrate and the bond coat, and that blocks or delays diffusion of aluminum from the bond coat into the substrate at high operating temperatures. This preserves aluminum in the bond coat that maintains a beneficial alumina scale (29) between the bond coat and the TBC. This delays spalling of the TBC, and lengthens the coating and component life.

    Abstract: A method of depositing a catalytically reactive coating to a substrate including selecting a target light off temperature for a predetermined catalytic combustion environment, selecting a thermal barrier coating composition, selecting a catalytic material and codepositing the thermal barrier coating composition and the catalytic material onto the substrate in proportions selected to produce the target light off temperature when exposed to the combustion environment. The method may include controlling the codepositing step to cause the thermal barrier coating composition to interact with the catalytic material to produce a phase having a light off temperature different from the respective light off temperatures of the thermal barrier coating composition and the catalytic material. A catalyst element may include a substrate and a first layer comprising a thermal barrier coating composition and a catalytic material throughout its depth disposed over a first portion of the substrate. Other portions of the catalyst element may have a second layer consisting of a catalytic material and a third layer consisting of a thermal barrier coating composition depending on a stage of combustion with a combustion environment.
