| Abstract: | The passivation behavior of insoluble anode from 8 kinds of Ti-base alloys in the 40% H_2SO_4(aq)and1 mol/L MnSO_4 -0.75 mol/L H_2SO_4 was studied respectively by analyzing potential-controlling stationarypolarization curve. Results indicate that the passivation curves of Ti-base alloy insoluble anode are analogousto that of pare titanium anodc in spite of the critical passivation current density i_b for the former is somewhathigher and passivation retaining current density i_p increases significantly, the passivation region diminishes.the passivation becomes not so clear. Ou the basis of electrochemical and X-ray diffraction data the passivationmechanism of pure titanium anode in EMD industry is discussed and authors suggest that the Ti- base alloyanode is better than the pure titanium anode. |
