摘要： A method of bonding a first article (12) to a second article (26), each article (12, 26) having a respective bond surface (14, 28). The method comprises interposing a porous interlayer region (16) between the bond surfaces (14, 28) of the first and second articles (12, 26) and subsequently using electrical resistance heating to locally heat the interlayer region (16) under contact pressure to a bonding temperature below the melting temperature of the interlayer (16) and the first and second articles (12, 26) to thereby bond the interlayer (16) to the first and second articles (12, 26) to form a bonded article. The interlayer (16) has a porosity of between approximately 10% and 30%

摘要： A method of manufacturing an article (32) by hot pressing and ultrasonically inspecting the article (32) comprises forming and filling a canister (80) with powder material and evacuating and sealing the canister (80). Heat and pressure are applied to the canister (80) to consolidate the powder material to form the article (32). The article (32) within the canister (80) is ultrasonically inspected by moving a transducer (124) over the whole of the canister (80). The position of an interface between the article (32) and the canister (80), and the thickness of the canister (80), at each position on the surface of the canister (80) and if there are defects within the article (32) are determined. The canister (80) is then removed from the article (32) by machining the canister (80) using a machining tool (148), the movement of the tool (148) is controlled such that at each position of the canister (80) the tool (148) removes the determined thickness of the canister (80) for the corresponding position on the surface of the canister (80).

摘要： Apparatus for manufacturing a component and a method of manufacturing a component, e.g. by material deposition. The method comprises the steps of directing a beam (20) of energy to heat a working region (56) of a substrate (32) and adjusting the cross sectional shape of the beam (20) to thereby generate a variety of predetermined cross sectional shapes of working region (56) while the beam (20) is being directed onto the substrate (32). Thus the distribution of energy delivered to the substrate (32) is controlled during the manufacturing process. The cross sectional shape and area of the beam (20) is repeatedly monitored and compared to a library (46) of predetermined cross sectional shape(s) and area(s).

摘要： A spray nozzle 10 for a laser deposition apparatus, comprises an elongate nozzle aperture 16, a powder supply chamber 18 in fluid communication with the elongate nozzle aperture and upper and lower elongate gas apertures 26, 28 located above and below the elongate nozzle aperture respectively and extending substantially parallel to the elongate nozzle aperture. In use the powder supply chamber supplies powder to the nozzle aperture under pressure so as to cause a wide powder stream to be ejected from the nozzle aperture and the upper and lower elongate apertures eject a wide gas stream above and below the wide powder stream. When used with a laser deposition apparatus 10 a relatively wide coating of a substantially uniform thickness can be deposited.
