Process for the production of composite components by powder injection molding, and composite powders suitable for this purpose |
摘要 |
The invention relates to a process for the production of metallic and metal-ceramic composite components by powder injection molding of a system comprising a metal composite powder, a binder and optionally a ceramic component, where the metal composite powder used is mixed with a protecting liquid in an inert atmosphere before the mixing with the binder. The invention furthermore relates to molybdenum/copper and tungsten/copper composite powders which have a primary metal particle size of predominantly <2 mum, an oxygen content of <0.8% by weight and optionally a ceramic component, to the use of these composite powders for the production of composite components by powder injection molding, and to a process for the preparation of composite powders in which oxides of molybdenum or tungsten and of copper are mixed, dry-ground and reduced using hydrogen at a temperature of from 800 to 1050° C., and a ceramic component is optionally admixed with the resultant metal composite powder.
