Method for producing a cemented carbide or ceramic metal powder using a resonant acoustic mixer

摘要

A method for producing a piece of cemented carbide or ceramic metal, comprising the steps of: forming a powder mixture comprising powders that form hard constituents and metallic binder; - subjecting said powder mixture to a mixing operation using a resonant non-contact acoustic mixer where acoustic waves are used that have a frequency that achieves resonance conditions to form a combination of mixed powders, where the frequency used is between -80 Hz, - subjecting said combination of mixed powders to a forming and sintering operation.
