Preparation, Characterization and Catalytic Performance of Nanometer Ceria-Zirconia Solid Solution Pan Junyan1,Hu Yucai1,Wang Yinghui1 (1.School of Chemistry and Material Sciences, Yantai Normal University, Yantai 264025, China) Abstract:Ce0.6Zr0.4O2 solid solution was prepared by co-precipitation technique using hydrazine hydrate as precipitator.Various physico-chemical techniques such as XRD......
of high quality[5]. 2 Experimental The goal of the experiments is to optimize the thixo- forming parameters. Four main forming parameters were studied: semi-solid material temperature; tool lubricant... friction forces, higher material fluidity and longer tool life. This type of semi-solid process requires high solid fraction (0.7s<1) materials because of its low......

for the development of new generation high-performance gas turbine engines[1]. Molybdenum disulfide is a widely used solid lubricant and performs best under dry conditions[2]. Its lubricating properties... that the chromium sulfide formed by reaction was also excellent solid lubricant. WU et al[4] prepared Ni/MoS2 self-lubricating composite by powder metallurgy method and found that mechanical properties......
