Abstract:
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.
