10 0 5; Simulation of current interrupt technique for measuring anodic overpotential of aluminum electrolysis and its genetic algorithm for optimization Abstract: Anodic overpotential was measured by current interrupt technique, and the quasi Newton method was used to determine the coefficient of overpotential decay equation . The result indicated......
STUDY OF ANODIC OVERVOLTAGE IN NEODYMIUM ELECTROLYSIS Q.Han1,K.R.Liu1,J.S.Chen1,X.J.Wei1 (1.School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China) Abstract:The anodic overvoltage of neodymium electrolysis was determined by slow scanning oscillogram. The effects of some factors, i.e. the temperature, the anodic current density, the concentration of Nd2O3......

Anodic passivation of Pb-Ag-Nd anode in fluoride-containing H2SO4 solutionZHONG Xiao-cong(钟晓聪), JIANG Liang-xing(蒋良兴), LIU Fang-yang(刘芳洋), LI Jie(李劼), LIU Ye-xiang(刘业翔) (School of Metallurgy... to the formation of a thick, compact and adherent passive film. Furthermore, pre-treatment in fluoride-containing H2SO4 solution also facilitates the formation of PbO2 on the anodic layer, and the reason could......
aspects: anodic potential, anodic corrosion rate, morphology and composition of the anodic oxidation film, purity and morphology of cathodic product. The results show that the porous anode can reduce the real anodic current density and decrease anodic oxygen evolution overpotential. For example, the oxygen evolution overpotential of Pb-Ag porous anode (pore diameter of 1.0-1.25 mm) is 131 mV......
