    摘要: Provided is joint part capable of suppressing diffusion of carbon and nitrogen contained in the steel member to the TiAl-based alloy member and suppressing formation of voids, titanium carbide or a nitride due to diffusion of carbon and nitrogen contained in the steel member, and thereby suppressing decrease in the brazing strength. A joint part comprises a steel member containing alloy elements including C and Cr, a TiAl-based alloy member, and a Ni-based brazing filler metal via which the steel member and the TiAl-based alloy member are joined to each other, wherein the steel member has a carbide and a nitride each forming a bond with at least one of the alloy elements at least on a side of a boundary with the Ni-based brazing filler metal, and diffusion of C and N to the Ni-based brazing filler metal adjacent to the TiAl-based alloy member is suppressed by the carbide and the nitride. The joint part may be a turbine body 1 comprising a turbine wheel 2 and a shaft 3, and a structural steel material of the shaft 3 is structural steel material containing 0.30 to 0.45 wt % of C and 0.85 to 1.25 wt % of Cr, or a martensitic stainless steel material containing at most 15 wt % of C and 11.5 to 13 wt % of Cr.

    摘要: A method of manufacturing an orthopaedic implant device having a porous outer surface is described. In one embodiment, the implant device includes a porous layer, an intermediate layer, and a solid substrate. The porous layer is preferably bonded to the intermediate layer by cold isostatic pressing. The intermediate layer is preferably bonded by vacuum welding to the solid substrate such that the porous layer forms at least a portion of the outer surface of the orthopaedic implant device. Preferably, a diffusion bond is created between the bonded intermediate layer and the solid substrate by hot isostatic pressing. In another embodiment, a porous layer is created on an outer surface of a solid layer by selective melting. Preferably, the solid layer is bonded to the solid substrate such that the porous layer forms at least a portion of the outer surface of the orthopaedic implant device.

    摘要: A method for producing a component of a turbomachine is disclosed. The method includes a) layer-by-layer deposition of a powder component material onto a component platform in a region of a buildup and joining zone, where the deposition takes place in accordance with layer information of the component to be produced; b) local layer-by-layer fusion or sintering of the powder component material by energy supplied in the region of the buildup and joining zone, where the buildup and joining zone is heated to a temperature just below a melting point of the powder component material; c) layer-by-layer lowering of the component platform by a predefined layer thickness; and d) repetition of steps a) to c) until the component is finished. A device for producing a component of a turbomachine is also disclosed.
