Study on the Performance and Corrosion Failure Process of Porous Titanium-Based Coated Electrodes

Titanium-based coated electrodes are considered to be a substitute for Pb-based anodes because of their lower weights and energy consumption; however, properties service lives affected by the matrix structure. Herein, metal oxide coating was prepared via thermal oxidation decomposition 5 μm-porous titanium plate. The scanning electron microscope (SEM) showed that on porous plate strengthened in each layer had pores. inner particles sized using nanometers, with diameter 22–64 nm compact electrochemical test results show that, compared flat plate, attached has better catalytic performance chlorine evolution reaction, (the potential decreases 121 mV), life is increased 3.78 times. Through SEM, XRD, EDS analysis composition after corrosion failure, mechanism surface discussed.
