Experimental Studies on Fretting Wear Behavior of PVDF Piezoelectric Thin Films.

From the experimental data and morphological characterization, the following conclusions are drawn: The friction coefficient of the PVDF thin films shows an increasing trend from 0.07 to 0.144 with the increase in displacement amplitude, and shows a decreasing trend from 0.115 to 0.081 with the increase in applied normal force under the setting condition.

However, the wear volume always shows an increasing trend with the increase in displacement amplitude.
