Title:
粉末射出成形により複合部材を製造する方法および前記方法に使用するために適した複合粉末
Document Type and Number:
Japanese Patent JP2004506815
Kind Code:
A
Abstract:
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.
