Abstract This article presents an experimental investigation on the fretting wear behavior of piezoceramics P51, PSnN5, and PLiS51 against an Si3N4 ceramic ball under air condition. A sphere-on-flat contact pattern is used as the contact model. The influence of displacement amplitude, frequency, and normal force is taken into account. After each test, friction logs are used to determine the contact interface state. A 3D topography measurement instrument is applied to measure the surface morphology and wear volume. Fretting wear on piezoelectric ceramics under different normal loads, frequencies, and displacement amplitudes are summarized through the collection and analysis of experimental data. It is found that, among the three piezoceramics, PLiS51 has the best wear resistance at higher displacement amplitude and frequency and P51 has the best wear resistance at greater normal force.
