Definitions

  • a first aspect of the invention in a method of manufacturing a composite generally cylindrical body at least two metallic powders are introduced into different parts of a thin-walled mould, the mould is closed and the mould and the powder therein are subjected to a compaction process to compact the powder into a solid body of the required dimensions and the compacted powder is sintered.
  • the mould and the powder therein are conveniently compacted by an isostatic process. This process can either take place at an ambient temperature or it may take place at an elevated temperature.
