The model allows for investigation of thermally induced changes in contact pressure and accompanying temperature and stress fields.

模型中考虑了由热引起的接触压力的改变以及随之改变的温度场和应力场。

The microstructure and morphology are examined by SEM, XRD, EPMA, and the electrochemical performance is studied by potentiodynamic polarization and current efficiency. The results show that the alloy elements in the electrode coating prepared by the sol-gel process are well distributed, more sufficient to form solid solution and with higher current efficiency than by the traditional thermal decomposition process. The deactivation effect is due to the forming of unconductive TiO2 for the sol-gel process, but due to the dissolution of active composition for the thermal decomposition process.
