Abstract: A process of synthesizing a yttrium aluminum garnet (YAG) powder. The process comprises introducing powders of yttria and silica to form a powder mixture, wherein alumina is not added to the powder mixture. Milling the powder mixture in the presence of an alumina grinding media and a solvent forms a powder slurry. Processing the powder slurry forms a green compact. Calcining the green compact at a temperature of from 1100° C. to 1650° C. for greater than 8 hours in air to 50% or less theoretical density forms a YAG compact of at least 92 wt % Y3Al5O12. Milling the YAG compact, without a grinding media, and drying produces the YAG powder. Processes further include introducing a dopant to the powder mixture to produce doped YAG powder.

Abstract: The present disclosure relates to a method of applying a wear-resistant copper-nickel-tin coating to a substrate using a thermal spray process. Briefly, a copper-nickel-tin alloy feedstock is converted into a powder or droplet form, then sprayed onto a substrate to form a coating thereon.

Abstract: A piston ring is made from a copper-beryllium alloy. This material permits the top compression ring of a piston to be moved closer to the piston crown, reducing crevice volume and reducing the tendency for pre-ignition. Ignition timing advance can be realized by installing the rings and letting the ECU advance the timing as the sensors allow, increasing efficiency. Also, shorter pistons and longer connecting rods are possible. The shorter pistons reduces the reciprocated mass in the engine and the longer connecting rods reduce the frictional loss caused by radial forces pushing the piston against the liner. Both reducing volume and tendency for pre-ignition increase engine efficiency.

Abstract: An apparatus and method for improving the performance of a vacuum coating system includes a vacuum chamber enclosing a track. The track is substantially rectangular having a top surface and a bottom surface. A pair of legs are attached to the bottom surface of the track and support the track within the vacuum chamber. The legs have a top edge engaging the bottom surface of the track and a bottom edge secured to a bottom section of the vacuum chamber. The legs extend longitudinally along the bottom surface of the track. A rail is mounted on the top surface of the track and extends along a longitudinal axis of the track. A substantially planar platter having a top face and a bottom face is supported on top of the rail. The platter is adapted to slide from side to side along the rail across the length of the track. A stage carrying an electron beam evaporator is mounted on the top face of the platter. As such, the electron beam evaporator slides with the platter across the length of the track.

Abstract: A process for depositing diamond crystals onto a field emission cathode. The process involves providing a cathode having a substrate, a gate layer and a plurality of emitters electrically insulated from the gate layer. An electric bias is applied to the gate layer and a ground potential is applied to the emitters. A heat source is positioned adjacent the cathode, and the cathode is exposed to a field of ions for a sufficient period to at least partially clean the emitters. A carbon containing gas is added to the atmosphere adjacent to the cathode such that carbon ions are dissociated from the gas and deposited on the emitters to form a "soot". The temperature of the cathode is then adjusted to a level which allows formation of diamond film.

Abstract: A process of operating a blast furnace characterized by the steps of employing silica enriched coke as the coke charge, and allowing the silica to react with condensed alkalies in the furnace to form alkali silicates and thereby minimize degradation of the coke during oxidation. A silica enriched coke especially adapted for blast furnace operations containing added silica in a minimum amount of about 1% by weight, and a method of making the same by dispersing and blending the silica in the coal in a minimum amount of about 0.7% by weight before coking.
