| Résumé : | This study describes synthesis of Fe–Cr alloy nanoparticles by using a method which couples electrodeposition of metals with the employment of high power ultrasound. The production of alloyed nanoparticles was performed using a 20 kHz titanium alloy horn ultrasound generator, a “sonoelectrode” generating short current pulses (tON) triggered and followed immediately by ultrasonic pulses (tUS). A rest time (tr) restores the initial conditions close to the sonoelectrode. The final product is a suspension of nanoparticles with high purity and high surface/volume ratio, which could be controlled by varying process parameters like time management and current density. |
