METHOD FOR WETTING A SONOTRODE AND SONOTRODE

The invention relates to a method which comprises the following steps: a) providing a first bath of a liquid metal (1) comprising aluminium with a content X and magnesium with a content Y, the content Y of magnesium being other than zero; b) at least partially dipping a sonotrode (3), made of a mate...

Beschreibung
Zusammenfassung:	The invention relates to a method which comprises the following steps: a) providing a first bath of a liquid metal (1) comprising aluminium with a content X and magnesium with a content Y, the content Y of magnesium being other than zero; b) at least partially dipping a sonotrode (3), made of a material that is inert in liquid aluminium, into the first bath of liquid metal (1); and c) applying powerful ultrasounds to the sonotrode (3) so as to energise the liquid metal (1) until the wetting (5) of the sonotrode (3) by the liquid metal (1) is achieved; d) cooling the first liquid metal (1) of the first bath until the first liquid metal (1) solidifies around the sonotrode (3), generating an intimate bond (6) between the sonotrode (3) and the first solidified liquid metal (1), said bond having a bond strength substantially equal to that of brazing between two metals; and e) machining the solidified first metal (1) in the shape of a clamp (7) configured for attaching a mechanical amplifier and/or a transducer (4).
