; 文献标志码:A 文章编号:1672-7207(2019)02-0452-08 Variation law of rainfall infiltration depth and saturation zone... of rainfall infiltration depth and saturation zone of slope with different rainfall conditions, soil types, surface matric suctions and slope ratios based on the finite element calculation theory......
) (State Key Laboratory of Powder Metallurgy (Central South University), Changsha 410083, China)Abstract:Before densification by chemical vapor infiltration, carbon or SiC nanofibers were grown... infiltration were investigated. The results show that the nanofibers improve the surface activity of the carbon fibers and become active nucleation centers during chemical vapor infiltration. They can induce......
; Abstract: The oxidation behavior of chemical vapor infiltration (CVI), molten silicon infiltration (MSI) and CVI+MSI C/SiC composites at 500-1 400 ℃ was studied. The oxidation below 900 ℃ increased... ℃ with oxidation process, exhibiting a self-catalytic characteristic. Key words: chemical vapor infiltration (CVI); molten silicon infiltration (MSI); C/SiC composites; oxidation  ......
Preparation and Arc Erosion Resistance of C_f/Cu Composite by Vacuum Melting Infiltration张华煜1,LIU Yiwen2,ZHAO Xianling1,LUAN Xingang21. College of Material Science and Engineering, Taiyuan University... composite was prepared by vacuum melting infiltration. Tiand Cr were doped to the Cu alloy to improve the wettability between Cu and carbon. The microstructure was investigated by XRD, SEM and EDS. The arc......
Effects of yttria content on the CMAS infiltration resistance of yttria stabilized thermal barrier coatings systemJuan J.Gomez Chavez1,Ravisankar Naraparaju2,Peter Mechnich2,Klemens Kelm2,Uwe...">The effects of YO1.5 doping in yttria-zirconia based thermal barrier coatings(TBCs) against CMAS interaction/infiltration are discussed.

SiCp preformed compacts obtained by pre-sintering process at 1150 K have high strength and good......
of Technology, Harbin 150001, China)Abstract:Ti-Al complex with a network microstructure was successfully fabricated by pressure infiltration. The fabricated Ti-Al complex was investigated and analyzed by OM, XRD, SEM and EDS. The temperature of pressure infiltration was reduced by using Al-Si eutectic alloy instead of pure Al, which can effectively decrease non-diffusion reaction between liquid Al......
