Abstract

A study of the fatigue behavior of hot-pressed PLZT (La-doped lead zirconate titanate) with composition 7/68/32 under different surface conditions is reported. It is found that the fatigue occurring at a few thousand of cycles is mainly caused by the contaminated surface instead of by intrinsic structure deterioration. For the same gold electrodes, samples with a conventionally cleaned surface showed significant fatigue within 105 switching cycles while samples with surfaces cleaned by an improved procedure did not show fatigue even after 108 switching cycles. The mechanism of fatigue introduced by surface contamination is explained by interface degradation between ceramic and electrode.
