    摘要： A process for chemically stripping a metallic coating on an external surface of a substrate without attacking an internal surface defined by an internal passage within the substrate. Processing steps include depositing within the internal passage a thermally-decomposable wax having a melting temperature above 75° C. so as to mask the internal surface of the substrate, and then treating the substrate with an aqueous solution containing an acid having the formula HxAF6 where A is silicon, germanium, titanium, zirconium, aluminum, or gallium, and x has a value of one to six. The aqueous solution is at a temperature below the melting temperature of the wax and substantially removes the metallic coating from the external surface of the substrate, while the wax is substantially unreactive with the aqueous solution and prevents the aqueous solution from contacting the internal surface of the substrate. Thereafter, the substrate is heated to thermally decompose the wax without producing hazardous byproducts.

    摘要： Multi-layer sensors are made using a direct write deposition technology. The sensors are formed on the surface of an object having a system characteristic to be monitored, such as temperature and strain. A first layer is deposited onto the substrate of the object to be monitored, a second layer is deposited onto the first layer, and a third layer is deposited onto the second layer. An optional protective layer may be deposited between the first layer and the substrate to prevent chemical interaction and lack of adhesion therebetween. A glazing or glassing layer may also be deposited to protect the thermistor from the operating environment to keep its electrical properties constant. These layers are sintered together, then electrical leads are attached to the sensor and to a monitoring controller. The monitoring controller may be hardwired to the sensor or remote therefrom.

    摘要： A mold is provided for enabling casting of single crystal metallic articles including a part-defining cavity, a sorter passage positioned vertically beneath and in fluid communication with the part-defining cavity, and a seed cavity positioned vertically beneath and in fluid communication with the sorter passage. The sorter passage includes a shape suitable for encouraging a single crystal structure in solidifying molten metal. Additionally, a portion of the mold between the sorter passage and the part-defining cavity includes a notch for facilitating breakage of a cast article proximate the notch during thermal stress build-up, so as to prevent mold breakage or the inclusion of part defects.
