Ultrasound-assisted wet media milling increases carbon dispersion and reduces the particle size simultaneously. The ultrasound is generated by a 20 kHz,500 W …

The advantage of ultrasonic vibration–assisted milling of titanium alloys has been reported generally under low material removal rate. In this study, high-speed longitudinal-torsion ultrasonic vibration milling (LTUVM) of Ti-6Al-4V was adopted to investigate the cutting forces and tool wear in contrast to conventional milling (CM). In …

Ultrasound-assisted wet media milling increases carbon dispersion and reduces the particle size simultaneously. The ultrasound is generated by a 20 kHz,500 W automatic tuning ultrasound probe. The maximum discharge rate of the LFP synthesized this way was achieved with cellulose as a carbon source, after 9 h milling, at 70% ultrasound …
