摘要： An apparatus for bonding a particle material to near net theoretical density, includes a chamber (26), a punch and die assembly (40) for supporting a particle material, plungers (58) for applying shear and/or axial pressures, and a power supply (PS) for applying a current. The apparatus may be used to bond metallic, ceramic, intermetallic and composite materials to near-net shape, directly from precursors or elemental particle material without the need for synthesizing the material. The apparatus may further be used to repair a damaged or worn substrate or part, coat a particle onto a substrate, and grow single crystals of a particulate material.

摘要： PCT No. PCT/GB94/01044 Sec. 371 Date Jun. 12, 1996 Sec. 102(e) Date Jun. 12, 1996 PCT Filed May 16, 1994 PCT Pub. No. WO94/27767 PCT Pub. Date Dec. 8, 1994A two layer valve seat insert and a method for its manufacture is described. The method comprises the steps of preparing two powder mixtures; a first powder mixture for forming the valve seat face layer; a second powder mixture for forming the valve seat base layer; sequentially introducing a predetermined quantity of each of said first and said second powder mixtures into a powder compacting die and having an interface therebetween substantially perpendicular to the axis of said die; simultaneously compacting said first and said second powder mixtures to form a green compact having two layers and sintering said green compact, wherein at least one of the chemical composition or the physical characteristics of at least one of said first and said second powder mixtures is adjusted so as to result in said valve seat face layer and said valve seat base layer having substantially the same density after compaction.

摘要： @ A piston ring is formed by annular upper and lower parts (10a, 10b) which contact one another at respective surfaces (12) normal to the axis of the piston ring. The parts can be injection moulded from thermoplastics materials with the parts themselves having no re-entrant portions, so allowing quick and easy manufacture, but with the parts together defining re-entrant portions such as a spring-receiving recess (16) at the inward side of the ring or a pair of spaced oil control rails (13) at the outward side of the ring.

摘要： A process of fabrication a corrosion and erosion resistant component. In one embodiemtn, the process entails applying one or more corrosion resistant materials onto a pre-formed, sacrifical core and then enclosing this first material and the core with a surrounding capsule. Any space within the capsule is then substantially filled with a second material, after which the capsule is sealed and treated to cause the second material to densify and to metallurgically bond to the first material. Thereafter, the core material and capsule are removed via chemical and/or mechanical processes to yield a component with a shape that approximates the space that existed between the capsule and the first material, and with an outer surface that reflects the shape of the outer surface that reflects the shape of the outer surface of the core and the inner surface of the capsule.

摘要： A method for making dies or molds from powdered metals is disclosed. The method includes the steps of: providing a pattern of a desired shape to define the mold or die cavity configuration (4); providing a canister (10); placing the pattern in the canister and filling the canister with a selected powdered metal (6); hot isostatic pressing the canister and powdered metal to produce a consolidated and densified compact; and sectioning the compact along a plane to enable removal of the pattern and thus provide the desired die or mold cavity in the fully densified powdered metal die or mold set so formed.

摘要： A novel process is disclosed by which contorted or distorted sheet gauge steel and other metal scrap material, generated by stamping and other deforming metal-working operations, is flattened by rolls (50,60) for the purpose of increasing the bulk density and to provide a scrap product that can more efficiently be transported and used for remelting in steel-making and foundry furnaces. The process involves the steps of feeding contorted sheet metal scrap between a pair of moving compressive surfaces, compressing the scrap to substantial flatness, and discharging the flattened steel scrap. The novel apparatus for performing the process is also disclosed.

摘要： A dual alloy cooled turbine wheel is manufactured by casting a hollow cylinder (1) of first nickel-base alloy material with high creep resistance to produce directionally oriented grain boundaries. A preform (2) of a second nickel-base alloy material with high tensile strength and high low-cycle-fatigue strength is diffusion bonded into the bore (1A) of the hollow cylinder (1) by subjecting the cylinder and preform to hot isostatic pressing. The resulting cylindrical block (10) is cut into thin precisely flat wafers (10A). A plurality of alignable holes (11, 11B) for forming fluid cooling passages are photochemically etched into the individual wafers. The wafers then are laminated together by vacuum diffusion bonding techniques, with the holes (11, 11B) aligned to form fluid cooling passages. The resulting laminated block (10B) is machined to produce the turbine wheel (10C) with turbine blades (13) through which the cooling passages (11, 45) extend.

摘要： A component, such as a turbine disk, made from a metal or metal alloy which has been processed to display superplastic properties at elevated temperatures, is diffusion bonded to a component or components, such as turbine blades, made from another metal or metal alloy, by disposing the components in a press with the surfaces to be bonded in mating contact. Moisture and oxygen are removed from between the surfaces. Heat and pressure are then applied, such as by forging at an elevated temperature or by hot isostatic pressing, to cause superplastic deformation of at least one of the components at the bonding surfaces. The heat and pressure are held sufficiently long to diffusion bond the surfaces. The new integral assembly is then heat treated to obtain desired properties. Consistently good diffusion bonds are achieved by this method.
