Method of making a cemented carbide body |
摘要 |
The present invention relates to a method of making a cemented carbide comprising the steps of first forming a powder blend comprising WC raw material powder and a metal binder phase powder, where the WC raw material is single crystal and where the WC grains after sintering have a spherical or angular morphology. The powder blend is then subjected to a mixing operation using a non-contact mixer wherein acoustic waves achieving resonance conditions to form a mixed powder blend and then subjecting said mixed powder blend to a pressing and sintering operation. The method makes it possible to maintain the grain size, the grain size distribution and the morphology of the WC grains. |
