Ultrasonic processing is applied to modify nanopowders of metals for the creation of composition alloys. The introduction of particles to metal is prevented by their low wettability in the metal melt. We use electrostatic charging of particles to increase the wettability of particles and to prevent their agglomeration. Mechanisms of the ultrasonic impact on melts of metals containing charged nanoparticles are considered. We find that an electric charge of the surface leads to a decrease in the contact angle. Expressions for the time of ultrasonic processing depending on physical and chemical characteristics of particles and the melt are found.
