    摘要： Scroll members for scroll compressors made from one or more near-net shaped powder metal processes, either wholly or partially fabricated together from sections. In certain variations, the involute scroll portion of the scroll member has a modified terminal end region. The terminal end region may include an as-sintered coupling feature comprising a tip component that forms a contact surface for contacting an opposing scroll member during compressor operation. The tip component can be a tip seal or a tip cap received by the as-sintered coupling feature. The tip cap may be sinter-bonded or otherwise coupled to the terminal end region. In other variations, a terminal end region may comprise a second material including a tribological material that forms a contact surface. Methods of making such scroll members for scroll compressors are also provided.

    摘要： Process for producing a shaped metallic body from a thermoplastic composition by injection molding or extrusion to form a shaped part, removal of the binder and sintering, wherein a thermoplastic composition composed of a metal powder and a polymer mixture B
    1 ) and B
    2 ) based on a polyoxymethylene homopolymer or copolymer B
    1 ) is used as binder and to remove the binder a) the shaped part is treated with a solvent which extracts the binder component B
    2 ) from the shaped part and in which the binder component B
    1 ) is insoluble, b) the solvent is then removed from the shaped part by drying and c) the shaped part is treated thermally at from 140 to 200°C in an oxygen- comprising atmosphere, as a result of which the binder component B
    1 ) is removed from the shaped part; and also a shaped metallic body which can be obtained in this way.
