METHOD OF MAKING A CEMENTED CARBIDE OR CERMET POWDER BY USING A RESONANT ACOUSTIC MIXER |
摘要 |
The present invention relates to a method of making a cemented carbide or a cermet body comprising the steps of first forming a powder blend comprising powders forming hard constituents and metal binder. 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. |
