Abstract: The method comprising 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 magnesium content Y being different to zero, b) Immersing at least partially a sonotrode (3) formed from a material inert to liquid aluminium, in the first bath of liquid metal (1), and c) Applying power ultrasounds to the sonotrode (3) so as to excite the liquid metal (1) until wetting (5) of the sonotrode (3) by the liquid metal (1) is obtained. d) Cooling the first liquid metal (1) of the first bath until solidification of the first liquid metal (1) around the sonotrode (3) is obtained, generating an intimate bond (6) between the sonotrode (3) and the solidified first liquid metal (1) having a bonding strength substantially equal to that of brazing between two metals. e) Machining the solidified first metal (1) in the form of a flange (7) configured for the attachment of a mechanical amplifier and/or of a transducer (4).

Abstract: The method comprises the following steps: a) Providing a sonotrode (1) formed from an essentially inert material with respect to the liquid metal, such as a ceramic, and preferably a silicon nitride or a silicon oxynitride, such as SIALON, or a metal essentially inert to said liquid metal, b) Immersing at least partially the sonotrode (1) in a bath of said metal, c) Applying to the sonotrode (1) power ultrasounds, particularly ultrasounds having a power greater than 10 watts to obtain the wetting of said sonotrode by said metal, d) Applying continuously to the sonotrode (1) measurement ultrasounds, also known as testing ultrasounds, particularly ultrasounds wherein the frequency is between 1 and 25 MHz, e) Applying intermittently to the sonotrode (1) power ultrasounds, particularly ultrasounds having a power greater than 10 watts, to maintain said wetting.

Abstract: The invention is a method for treating a solid substrate, made from a first material, of metal or ceramic type, the method comprising placing the substrate in contact with a liquid metal, while the substrate is exposed to an ultrasonic wave called a power wave. At the level of a surface of the substrate, the power density is greater than a cavitation threshold of the liquid metal. Such exposure improves the wettability of the substrate surface by the liquid metal.
