  • Method for connecting sintered body to a metallic support element
    Patent number: 6610244
    Abstract: The invention relates to a method for connecting a metallic support element to at least one body consisting of a powder metallurgical sintered material. The method is characterised in that said body is brought into contact with the support element in the form of a green body which is compacted from a sintered powder, in that a thin, flat copper body is brought into contact with the green body respectively and in that the entire resulting arrangement is heated to the temperature required to sinter the green body before being cooled again once the sintering process is complete.
    Type: Grant

  • Compacting auxiliary agent for producing sinterable shaped parts from a metal powder
    Patent number: 6224823
    Abstract: The invention relates to a process for producing sinterable metallic shaped parts from a metal powder, which is mixed with an auxiliary compacting agent containing at least in part components from the polyalkylene glycol family, is filled into a compacting mold and, following the compacting under pressure, is ejected from the mold as compacted shaped part.
