本研究表明,电极化抑制氧化钇稳定的氧化锆(YSZ)的低温降解(LTD)。电极化,这是由热刺激去极化电流(TSDC)的测量证实,由所施加的直流电压引起的。诱导极化导致亲水表面。表面的亲水性越强,它们就越能抵抗降解。我们提出了一种机制,LTD抑制中的电斥力引起的极化防止水的入侵到内部的YSZ。
This study demonstrates that electrical polarization inhibited low-temperature degradation (LTD) of yttria-stabilized zirconia (YSZ). Electrical polarizations, which were confirmed by the thermally stimulated depolarization current (TSDC) measurements, were induced by an applied dc voltage. The induced polarizations caused hydrophilic surfaces. The more hydrophilic the surfaces became, the more resistant they became to degradation. We propose a mechanism of LTD inhibition in which the electric repulsive force induced by the polarizations prevented the invasion of water into the inner part of the YSZ.
