摘要： Transparent optical ceramic coating materials have been fabricated from europium-doped lutetium oxide (Lu2O3:Eu) using physical vapor deposition and chemical vapor deposition techniques. The non-pixilated film coatings have columnar microcrystalline structure and excellent properties for use as radiological scintillators, namely very high density, high effective atomic number, and light output and emission wavelength suitable for use with silicon-based detectors having a very high quantum efficiency. The materials can be used in a multitude of high speed and high resolution imaging applications, including x-ray imaging in medicine.

摘要： A chemical vapor deposition process in which an internal reactor is disposed within a chemical vapor deposition reactor including means for enclosing a reaction chamber and means for heating the reaction chamber. The position at which the internal reactor is disposed relative to the heating means is selected to provide control of the temperature within the internal reactor. At least two solid precursor materials are placed in the internal reactor and are contacted with at least one precursor gas, reactive with the solid precursor materials to produce at least two reactant gases. These gases are directed to the reaction chamber to react with one or more additional reactants.

摘要： An oxidation resistant, high temperature thermal cycling resistant coated ceramic article for ceramic heat engine applications. The substrate is a silicon-based material, i.e. a silicon nitride- or silicon carbide-based monolithic or composite material. The coating is a graded coating of at least two layers: an intermediate AlN or Al.sub.x N.sub.y O.sub.z layer and an aluminum oxide or zirconium oxide outer layer. The composition of the coating changes gradually from that of the substrate to that of the AlN or Al.sub.x N.sub.y O.sub.z layer and further to the composition of the aluminum oxide or zirconium oxide outer layer. Other layers may be deposited over the aluminum oxide layer. A CVD process for depositing the graded coating on the substrate is also disclosed.

摘要： A process for producing a wear resistant article, such as a cutting tool. Gaseous halides of two or more of aluminum, zirconium, and yttrium with other reactants are passed over a cemented carbide substrate at 900.degree.-1250.degree. C. and 1 torr to about ambient pressure to form a composite ceramic coating on the substrate. The coating is a continuous first-phase metal oxide matrix having particles of at least one different metal oxide dispersed therein. In a preferred process, one or more of the metal halides is pulsed into the gaseous mixture containing a different metal halide to control the deposition of the particles.
