| 1 | Properties and microstructure of NiO/SDC materials for SOFC anode applications显示文摘NiO/SDC composites and Ni/SDC cermets for solid oxide fuel cell (SOFC) anode applications were prepared from nickel oxide(NiO)and samaria doped ceria (SDC) powders by the powder metallurgy process. The physical and mechanical properties, as well as the microstructure of the NiO/SDC composites and the Ni/SDC cermets were investigated. It is shown that the sintering temperature of the NiO/SDC composites and NiO content plays an important role in determining the microstructure and properties of the NiO/SDC composites, which, in turn, influences the microstructure,electrical conductivity, and mechanical properties of the Ni/SDC cermets. The present study demonstrated that composition and tprocess parameters must be appropriately selected to optimize the microstructure and the properties of NiO/SDC materials for solid oxide fuel cell applications. | CHENG Jigui DENG Liping ZHANG Benrui SHI Ping MENG Guangyao | 2007 | Rare Metals2007，26，2： | 3 |

| 6 | Novel confinement combustion method of nanosized WC/C for efficient electrocatalytic oxygen reduction显示文摘Nanosized tungsten carbide(WC)/carbon(C)catalyst was synthesized via a novel ultra-rapid confinement combustion synthesis method.The amount of activated carbon(AC)plays an important role in the morphology and structure,controlling both the precursor and final powder.The WC particles synthesized inside the pores of the AC had been 10-20 nm because of the confinement of the pore structure and the large specific surface area of AC.When used for oxygen reduction performance,the half-wave potential was−0.24 V,and the electron transfer number was 3.45,indicating the main reaction process was the transfer of four electrons.The detailed electrocatalytic performance and underlying mechanism were investigated in this work.Our study provides a novel approach for the design of catalysts with new compositions and new structures,which are significant for promoting the commercialization of fuel cells. | Pengqi Chen Yunxiao Tai Huan Wu Yufei Gao Jiayu Chen Jigui Cheng | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，8： | 1 |

| 11 | Microstructure and Tribological Properties of Laser Clad Ni-Ag/TiC Composite Coating显示文摘Ni-Ag/TiC composite coating was prepared on the 45 steel substrates by means of laser cladding. Microstructure and wear properties of composite coatings were analyzed using optical microscopy, field emission scanning electron microscopy and wear machine. The experimental results show that defects, such as cracks and pores, do not occur in the laser-cladded Ni-Ag/TiC composite coating and 45 steel substrate, and they present good metallurgical bonding between them. Compared with Ni/TiC composite coating, microhardness values of the two coatings do not present evident differences. The wear experiment result shows that Ni-Ag/TiC composite coated with Ag possesses low friction coefficient and good wear resistance compared with Ni/TiC composite coating. | 朱流 罗来马 WU Yucheng CHENG Jigui | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，2： | 0 |
