Effect of Titania Additive on Structural and Mechanical Properties of Alumina–Fluorapatite CompositesAwatef Guidara,Kamel Chaari,Jamel Bouaziz摘 要:Mechanical properties of alumina-fluorapatite composites with different titania additive amounts (0, 0.5, 1, 1.4, 2, 3, 4 and 5 wt%) have been investigated between 1200 and 1600℃. The optimum values......
Wire and arc additive manufacturing of 4043 Al alloy using a cold metal transfer methodZhi-qiang Liu1,2,Pei-lei Zhang1,2,Shao-wei Li1,2,Di Wu1,2,Zhi-shui Yu1,21. School of Materials Engineering... pulse(C + P) arc was applied in the additive manufacturing of 4043 Al alloy parts. Parameters in the manufacturing of the parts were investigated.

Shape controlled synthesis and tribological properties of CeVO4 nanoparticles as lubricating additive刘凤珍1,邵鑫1,2,3,尹贻彬1,3,赵利民1,3,邵珠伟1,刘雪华1,孟宪华11. College of Materials Science and Engineering... nanoparticles as additives in liquid paraffin were evaluated on a four-ball tester. The results indicated that the wear resistance was im-proved by the additive CeVO4 nanoparticles which exhibited very......
this study,a localized highconcentration electrolyte(LHCE) is formulated with1 wt% SbF3 as an interface-stabilized additive to protect the Na metal anode.This reformulated LHCE retains the special coordination structure in HCE with improved wettability and high ionic conductivity.Moreover,the introduction of the SbF3 additive into the LHCE resulted in a bilayer-structured solid electrolyte interface(SEI......

Metal Fabrication by Additive Manufacturing Using Laser and Electron Beam Melting TechnologiesLawrence E. Murr1,2,Sara M. Gaytan1,2,Diana A. Ramirez1,2,Edwin Martinez1,2,Jennifer Hernandez1,2,Krista...) are relatively new rapid, additive manufac- turing technologies which can allow for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor......
aluminum) were measured on aluminum surface (Alloy 1145) by sessile drop technique on an OCA35 dynamic contact angle tester. The effect of additive on the drop spreading was investigated as well... with time. In contrast to the stock oil, although addition of polarity additive of long chain alkyl into stock oil is able to decrease the surface tension of solutions, it weakens the wetting dynamic......
. Research on the effect of additive on selective reduction of the laterites ores with low nickel and high iron content[J]. Journal of China University of Mining & Technology, 2013, 42(5): 838-844... to improve the carbothermal reduction rate and iron metallization rate of nickel slag was used. The additive and the nickel slag were mixed in proportion and added with an appropriate amount of reducing......
