    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.
