摘要： A method for improving the fracture toughness for aluminum-based diffusion coatings by thermal spray means to simultaneously apply aluminum, chromium, boron, and/or silicon onto a steel workpiece, followed by heat treatment of the workpiece for a sufficient time to cause the aluminum, chromium, boron, and/or silicon to diffuse into the workpiece. The resulting diffusion coating demonstrates improved fracture toughness and does not necessitate the use of a slurry.

摘要： An article having a spallation resistant TBC comprises a metal substrate, such as a high temperature superalloy, and a TBC, such as a coating of yttria stabilized zirconia. The TBC comprises a plurality of plasma-sprayed layers. The TBC has a coherent, continuous columnar grain microstructure, wherein at least one layer has a plurality of continuous columnar grains which have been extended by directional solidification into an adjacent layer. In a preferred embodiment, the coherent, continuous columnar microstructure comprises substantially all of the volume of TBC. A coherent, continuous columnar grain microstructure is also taught wherein at least some of the plurality of coherent, continuous columnar grains which comprise a TBC extend through essentially the entire thickness of the coating. A columnar crack pattern of cracks extending generally normal to the surface of the metal substrate is also developed within TBCs of the present invention in conjunction with the coherent, continuous columnar grain microstructures described.

摘要： A system and method for depositing a CVD diamond coating on a non-planar surface of an object is provided. The system includes a deflector having a deflecting surface which resists diamond coating by the diamond forming reagents produced by the system and which is adapted to withstand the relatively high deposition temperatures is provided. The deflector is positioned substantially axially with an axis of the distribution head of the CVD engine. The deflector is preferably generally wedge-shaped or conical and coupled to a motor which is adapted to rotate the deflector at a relatively high speed. A mandrel may be positioned about or to one side of the deflector. The deflector is oriented with respect to the distribution head and the mandrel such that a jet exiting the distribution head is deflected by the deflector onto a surface of an object positioned on the mandrel. The object surface may be non-planar.

摘要： A thermodynamically stable, protective coating layer is applied by thermal spray technique to the inner and outer surfaces of a quartz crucible used for mono or polycrystalline silicon crystallization processing, inhibiting fusion between the silicon melt and the vitreous silica of the crucible, contamination of the silicon melt by contaminants released from the crucible by devitrification, and any chemical reaction occurring between the crucible and any supporting graphite structure. A powdered form of a suitable protective coating material compatible with high temperature plasma spray techniques, such as magnesium zirconate, barium zirconate, or stabilized zirconium oxide, is fed into a high temperature and high speed plasma jet directed at the crucible. The powder particles are softened or melted in the jet and deposited on the surfaces of the quartz crucible, and allowed to cool and harden into a protective coating.
