Preliminary Study of Oxygen Evolution Ti-Al Composite Anode
This text used by hot-pressing diffusion welding to obtain Ti-Al laminated composite anode.The interfacial morphology and interface reaction of Ti-Al laminated composite anode were analyzed by means of scanning electron microscopy(SEM) and EDS. The Ti/IrO2-Ta2O5 were got by typical oxygen evolution model coating ingredient(mole ratio of Ir to Ta was 7:3) and the sides of Titanium were examined by using electrochemical workstation.This text results indicated that the interfacial thickness varied from 462nm to 792nm with the increase of holding time and increased from 396nm to 1.25µm with temperature rising. Under the same condition of hot-pressing diffusion welding,the thickness of diffusion interface layer with aluminum sheets by previous cold rolling (1.25µm) is thicker than non-cold rolling(924nm),increasing by 35.28%. Ti-Al laminated composite anodes by using hot-pressing diffusion welding showed better performances than the industrial titanium.The oxygen evolution anode showed the best performance by holding at 833 K for 2h under the pressure of 6MPa.This will play a role in the energy saving.
