Abstract: This invention relates to the synthesis of Al/SiC based functionally gradient materials using a new technique termed here as gradient slurry disintegration and deposition. Gradients of SiC were successfully established using this technique for the starting weight percentages up to 20%. The results were confirmed using microstructural characterization techniques and microhardness measurements. Functionally gradient materials synthesized using this method holds the promise where differential tribological characteristics and the strength/toughness combinations may be required from the opposite surfaces.

Abstract: In the course of the reduction of metal salts powder such as a ternary oxalate of Fe, Co and Ni by heating in a reducing atmosphere, a nitrogen-containing compound gas such as NH3 is introduced into the reaction system atmosphere in order to form a layer of metal nitride on the surface of the powder. The nitride layer protects the resulting alloy powder against air-oxidation and deterioration in the magnetic properties.

Abstract: A bonded structure is a structure in which two bonding target members and a bonding portion formed between and adjacent to the bonding target members are bonded together. The bonding portion is made of a material mainly containing copper. In a cross section of the bonded structure taken along a thickness direction, a ratio of a bonded rate between the bonding target members and the bonding portion in a peripheral region of the bonded structure to a bonded rate between the bonding target members and the bonding portion in a central region of the bonded structure is from 0.6 to 0.9. The bonded rate is 0.3 or more.

Abstract: It has been found that duplex monolithic parts can be manufactured in high volume at low cost by using powder metal technology to mold and sinter an inner component of the part into an outer component of the part. This technique reduces the cost of manufacturing intricate metal products by taking advantage of the attributes of powder metal technology in making the inner component of the part. The outer component of the part can be wrought machined, stamped or forged, or made by double press double sinter or forging a powder metal component of the part. In any case, this technique can beneficially be used in making a wide variety of toroid parts, such as gears, clutches, sprags, bearing races, one-way diodes, and the like.
