Abstract

The results of studying the phase-structural transformations on the surface of piezoelectric ceramics of the lead zirconate titanate system under repeated dosed plasma exposure to enhance the resistance to extreme heat loads is presented. The formation of lead-free modified subsurface layer containing ZrTiO4 nanocrystals is confirmed as a result of 10 exposure cycles with 20 MW/(m2 √s) heat load per cycle. The stabilization of the polarization properties is observed under a further increase in the heat load up to 100 exposure cycles.
