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.
