Pb_3O_4层引入对钛基PbO_2电极强化寿命的影响

Effect of Pb_3O_4 Layer Introduction on the Accelerated Life of the Ti-PbO_2 Electrodes

在SnO2-Sb中间层的基础上,通过热分解引入Pb3O4层以提高二氧化铅层与钛基体的结合力,进而达到提高钛基二氧化铅电极寿命的目的。结果表明,Pb3O4层的引入使得钛基二氧化铅电极的强化测试寿命由100.5h提高到970h。根据XRF、XRD及SEM测试结果,详细分析了由于Pb3O4层的引入而提高PbO2电极强化寿命的原因。

By means of thermal decomposition, Pb3O4 layer was introduced into the Ti/SnO2-Sb electrode to increase the electrode service life through increasing the cohesive force between PbO2 and Ti. The results show that the introduction of the Pb3OO4 layer greatly enhances the accelerated test life of the PbO2 electrode from 100.5 h to 970 h. The enhancement causes of the accelerated life for the PbO2 electrode due to the introduction of the Pb304 layer were analyzed based on the results of XRF, XRD and SEM.
