Title: Effect of microstructure on the sonotrode properties of tool materials Ferro-titanit® WFN and steel CPM 10V®
Author: Š. EMMER, P. BAKSA, J. KOVÁČIK

Abstract: Two patented tool materials cermet Ferro-titanit® WFN and steel CPM 10V® are evaluated from the point of view of their sonotrode properties. The comparison criterion was ultrasonic energy transmission for each tool material. The maximum oscillation amplitude at lowest input power at a constant resonant frequency of 30 kHz and given voltage was measured. Both particulate composite systems are prepared by the methods of powder metallurgy thus having high structural homogeneity. Structural analysis showed that the cermet Ferro-titanit® WFN is a particulate composite material having aggregated hard TiC phase within the matrix. On the contrary, steel CPM 10V® is a particulate composite material with segregated and homogeneously dispersed hard VC phase within the matrix. The difference in the spatial distribution and aggregation/segregation of hardening phase within the matrix is a key factor that affects their ability to transmit ultrasound energy.
