Results of the X-ray diffraction and scanning electron microscopic analysis of morphological changes in the piezoelectric PZT ceramic surface before and after plasma irradiation are presented. It is shown that repeated exposure to high energy density hydrogen plasma flows leads to a significant change in the structure and elemental composition of the near-surface layer. At the same time, bulk piezoelectric properties of the material change only slightly.
