    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.

    Abstract: A method (50) of instrumenting a component (10) having a barrier coating (14). A sensor (76) is embedded within or below the coating. Material forming the sensor is deposited within a trench (80) formed into the barrier coating. The trench is then backfilled with material (70) to protect the sensor from the environment within which the component is operating. In this manner, the sensor may be embedded at any desired location and any desired depth within a barrier coating on a previously fabricated component. An array of sensors (98, 100, 102) may be embedded across the depth of the coating to provide signals indicative of operating conditions across the coating. The signals may be conducted to a connection location (24) by conductors (62, 64) that are deposited within the trench. The trench may be formed with a laser engraving process (54) and the material for the sensor and conductors may be deposited with a selective laser melting process (58).

    Abstract: A method for forming light-weight composite metal castings incorporating metallurgically bonded inserts for a variety of applications. Castings formed by the invention have particular utility as components of an internal combustion engine. A casting method includes the step of coating the insert with a first layer under conditions including sufficient temperature to cause a portion of the layer to be sacrificed by dissolving into the cast metal material while leaving at least a portion of the first layer as a diffusion barrier between the insert and the cast material. The molten casting material is treated and handled to keep the hydrogen content below 0.15 and preferably below 0.10 parts per million. The casting step takes place under a protective gas environment of dry air, argon or nitrogen with a moisture content of less than 3 parts per million.
