    Abstract: An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed. The cap can be used with the belted mold assembly or with a casting assembly known in the prior art.

    Abstract: A bronze alloy having a metallographic structure which has a fine multilayer structure constituted of a layer of α-form copper and a layer of a copper-tin intermetallic compound and includes an eutectoid phase comprising, dispersedly precipitated therein, fine metal grains containing at least bismuth (fine bismuth grains, etc.). The proportion of the lamellar eutectoid phase is 10-70% by area. From the standpoint of composition, the bronze alloy comprises copper and tin as main components and contains nickel, bismuth, and sulfur as additive elements, the nickel content being 0.5-5.0 mass %, the bismuth content being 0.5-7.0 mass %, and the sulfur content being 0.08-1.2 mass %. The tin content preferably is 8-15 mass %. The alloy may further contain lead in a proportion of 4 mass % or lower. The bronze alloy is used as a sliding surface of a sliding member (e.g., a hydraulic cylinder block).

    Abstract: A pelletizing die plate is useful with a main die body with passageways. The pelletizing die plate includes a die plate body, which is made of a hard composite material. The hard composite material contains a low thermal conductivity matrix of hard matrix particles and an infiltrant alloy bonded to the hard matrix particles to form the hard composite material. The hard matrix particles includes between greater than zero and up to about 20 weight percent titanium carbide particles and the balance cast tungsten carbide particles. The infiltrant alloy contains at least one or more of nickel and copper. The hard matrix particles are between about 50 weight percent and about 70 weight percent of the hard composite material and the infiltrant alloy are between about 30 weight percent and about 50 weight percent of the hard composite material. The hard composite material has a thermal conductivity less than or equal to about 25 Watt/m° K. The die plate body has bores in alignment with the passageways in the main die body thereby forming continuations of the passageways of the main die body. A method of making a pelletizing die assembly that has the steps of: providing a main die body wherein the main die body having a first end face and a second end face, and a plurality of passageways extending through said main die body between said first and second end faces; placing a first mass of hard matrix particles on the second end face of the main die body; placing a second mass of infiltrant alloy on the first mass of hard matrix particles; heating the first mass and the second mass whereby the infiltrant alloy infiltrates the first mass to form a hard composite material comprising a solid mass of the hard matrix particles bonded together by the infiltrant alloy; and forming bores in the hard composite material to form a top die plate wherein the bores are in alignment with the passageways in the main die body.
