| 3 | Electrodeposition of Ni-W Amorphous Alloy and Ni-W-SiC Composite Deposits显示文摘Ni-W alloys and their composite deposits are electroplated on the metals when an appropriate complex agent is selected on the base of the theories of electrochemistry and complex chemistry, and the principle of induced codeposition. Effects of the bath composition, pH value, temperature and current density on the electrode position of Ni-W alloys and their composite deposits have been investigated, and the effect of heat treatment temperature on the hardness, structure and cohesive force of the amorphous Ni-W alloys and their composite deposits are also discussed. Results showed that the alloys containing more than 44 wt pct W content and the composite deposits containing 7.8 wt pct SiC content could be obtained by making use of the appropriate bath composition and plating conditions. Alloys and their composite deposits with over 44 wt pct W content show amorphous structure. The hardness of amorphous Ni-W alloys and their composite deposits increases obviously when heated, and can reach to 1350 HV and 1520 HV respectively for 46 wt pct W content. The cohesion on Cu, carbon steel and stainless steel is very good. | Zhongcheng GUO, Xiaoyun ZHU, Dacheng ZHAI and Xianwan YANG (Department of Metallurgy, Kunming University of Science and Technology, Kunming 650093, China) | 2000 | Journal of Materials Science & Technology2000，16，3： | 9 |

| 6 | Effect of the current density on electrodepositing alpha-lead dioxide coating on aluminum substrate显示文摘The α-PbO2 electrodes are prepared by anodic electrodeposition on A1/conductive coating electrode from alkaline plumbite solutions in order to investigate the effect of the different current densities on the properties of α-PbO2 electrodes. The physic-ochemical properties of the α-PbO2 electrodes are analyzed by using SEM, EDS, XRD, Tafel plot, linear sweep voltammetry (LSV) and A.C. impedance. A compact and uniform layer of lead dioxide was obtained at the current density of 3 mA·cm-2. A further increase in current density results in smaller particles with high porosity. EDS and XRD analyses have shown that the PbO2 deposited in alkaline conditions is highly non stoichiometric, and the PbO impurities are formed on the surface layer besides the α-PbO2. The corrosion resistance of α-PbO2 at the low current density is superior to that of the high current density. It can be attributed to a porous layer of deposited films at high current densities. When used as anodes for oxygen evolution in aqueous Zn2+ 50 g·L-1, H2SO4 150 g·L-1, the Al/conductive coating/α-PbO2 exhibits lower potential compared to Pb electrode. Al/conductive coating/α-PbO2 electrode with the best electrocatalytic activity was obtained at current density of 1 mA·cm-2. The lowest roughness factor was obtained at 1 mA·cm-2. | Burning CHEN Zhongcheng GUO Hui HUANG Xianwan YANG Yuandong CAO | 2009 | Acta Metallurgica Sinica(English Letters)2009，22，5： | 6 |
| 7 | Electrochemical Properties and Microstructure of Al/Pb–Ag and Al/Pb–Ag–Co Anodes for Zinc Electrowinning显示文摘The Al/Pb–0.8%Ag and Al/Pb–0.75%Ag–0.03%Co(in mass fraction) anodes used in zinc electrowinning are prepared through the electrodeposition of lead methanesulfonate electrolyte onto an aluminum matrix.The results of anode polarization curves,Tafel curves,and EIS characterizations indicated that the Al/Pb–0.75%Ag–0.03%Co anode has higher electrocatalytic activity and corrosion resistance than the Al/Pb–0.8%Ag anode.SEM observations on the fruit surfaces demonstrated the crystals on the Al/Pb–0.8%Ag anode are larger than on the Al/Pb–0.75%Ag–0.03%Co anode.After 24 h of anodic polarization,SEM observations and XRD analysis showed that the MnO2–PbO2layer on the Al/Pb–0.75%Ag–0.03%Co anode surface is characterized by dendritic crystals,and the PbSO4–PbO2layer under the MnO2–PbO2layer is characterized by uniform and chaotic orientation tetragonal symmetry crystallites of PbSO4.However,the MnO2–PbO2layer on the Al/Pb–0.8%Ag anode surface is characterized by granular crystals,and the PbSO4–PbO2layer under the MnO2–PbO2layer is characterized by well-organized orientation crystallites of PbSO4,which are concentrated in certain zones. | Yongchun Zhang Buming Chen Zhongcheng Guo | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，2： | 5 |
| 8 | Properties of Al/Conductive Coating/α-PbO2-CeO2-TiO2/β-PbO2-WC-ZrO2 Composite Anode for Zinc Electrowinning显示文摘The properties of Al/conductive coating/α-PbO_2-CeO_2-TiO_2/β-PbO_2-WC-ZrO_2 composite anode for zinc electrowinning were investigated. The electrochemical performance was studied by Tafel polarization curves(Tafel), electrochemical impedance spectroscopy(EIS) and corrosion rate obtained in an acidic zinc sulfate electrolyte solution. Scanning electron microscopy(SEM), X-ray diffraction(XRD), and energy dispersive X-ray spectroscopy(EDXS) were used to observe the microstructural features of coating. Anodes of Al/conductive coating/α-PbO_2-CeO_2-TiO_2/β-PbO_2, Al/conductive coating/α-PbO_2-CeO_2-TiO_2/β-PbO_2-WC, Al/conductive coating/α-PbO_2-CeO_2-TiO_2/β-PbO_2-ZrO_2, and Pb-1%Ag anodes were also researched. The results indicated that the Al/conductive coating/α-PbO_2-CeO_2-TiO_2/β-PbO_2-WC-ZrO_2 showed the best catalytic activity and corrosion resistant performance; the intensity of diffraction peak exhibited the highest value as well as a new PbWO_4 phase; the content of WC and ZrO_2 in coating showed the highest value as well as the finest grain size. | 杨健 陈步明 GUO Zhongcheng HUANG Hui XU Ruidong JIN Bingjie | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，3： | 2 |
| 9 | Effects of Zr content on electrochemical performance of Ti/Sn-Ru-Co-ZrO_(x)electrodes显示文摘The low cell voltage during electrolytic Mn from the MnCl_(2) system can effectively reduce the power consumption.In this work,the Ti/Sn−Ru−Co−Zr modified anodes were obtained by using thermal decomposition oxidation.The physical parameters of coatings were observed by SEM(scanning electron microscope).Based on the electrochemical performance and SEM/XRD(X-ray diffraction)of the coatings,the influence of Zr on electrode performance was studied and analyzed.When the mole ratio of Sn−Ru−Co−Zr is 6:1:0.8:0.3,the cracks on the surface of coatings were the smallest,and the compactness was the best due to the excellent filling effect of ZrO_(2)nanoparticles.Moreover,the electrode prepared under this condition had the lowest mass transfer resistance and high chloride evolution activity in the 1mol%NH_(4)Cl and 1.5mol%HCl system.The service life of 3102 h was achieved according to the empirical formula of accelerated-life-test of the new type anode. | Linhui Chang Sheng Chen Xionghui Xie Buming Chen Haihong Qiao Hui Huang Zhongcheng Guo Ruidong Xu | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，12： | 1 |
