摘要： A method of forming a component includes defining an identification pattern, defining one or more scanning parameters and/or one or more heating parameters, depositing a sinterable material on a substrate and scanning a heat source of the deposited sinterable material to thereby selectively sinter the material to the substrate to produce a sintered layer having the identification pattern. The sintered layer includes first and second regions, and the method includes sintering the first region using one or more scanning parameters and/or one or more heating parameters having a first value, and sintering the second region using one or more scanning parameters and/or one or more heating parameters having a second value to thereby produce the identification pattern including a contrast between the first and second regions.

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

摘要： A method of forming a bonded assembly (10). The method comprises: providing at least first and second parts (12, 14) of an assembly (10) to be bonded; assembling the first and second parts (12, 14) in a required relative position to define a bond interface region therebetween; sealing part way along an edge (18) of the bond interface region using laser beam welding to define a cavity between the first and second parts (12, 14); in a vacuum environment, sealing the remainder of the edge (20) of the bond interface region using electron beam welding to form a fluid tight seal around the cavity; and applying heat and pressure to an external surface of the cavity to diffusion bond the first and second parts (12, 14) together.

摘要： There is proposed a method of surface-treating a cast intermetallic component, which is intended primarily to reduce or remove surface porosity from the component. The method includes the steps of: providing a cast intermetallic component; placing the component in an inert atmosphere; focussing a laser beam on a surface of the component; traversing the laser beam over at least a region of said surface whilst the component is in said inert atmosphere; and controlling the laser beam during said traversing step so as to locally melt the intermetallic material of the component to a depth of no more than 300 μm, as measured from said surface of the component.

The planet carrier includes a first ring, second ring spaced axially from the first ring, a plurality of circumferentially spaced axles and a plurality of circumferentially spaced support structures extending axially between and secured to the first ring and second ring. Each planet gear is rotatably mounted on a respective one of the axles. The first ring has a plurality of circumferentially spaced recesses and the second ring has a plurality of circumferentially spaced recesses. Each recess in the second ring is aligned with a corresponding one of the recesses in the first ring. A first end of each support structure locates in a recess in the first ring.
