by using the improved air permeameter. The impacts of initial water content, wetting and drying processes on the air permeability ka were analyzed. The conceptual model, super depth of field microscope.... Due to the permeation of the air and water during the wetting processes of the undisturbed and remolded loess samples and the formation of micro cracks during the drying process, the ka in the drying......
Engineering, Shenyang 110034, China 2) Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China摘 要:The wetting behavior of molten Zr55Cu30Al10Ni5 on Al2O3 and ZrO2 was studied using the sessile drop method. The results show that the nonwetting-to-wetting transition for the Zr55Cu30Al10Ni5/ZrO2 wetting system takes place at 1193 K......
Trans. Nonferrous Met. Soc. China 28(2018) 1784-1792 Wetting of molten Sn-3.5Ag-0.5Cu on Ni-P(-SiC) coatings deposited on high volume faction SiC/Al composite Xiang-zhao ZHANG1, Xiao-lang WU1, Gui-wu... October 2017 Abstract: The wetting of molten Sn-3.5Ag-0.5Cu alloy on the Ni-P(-SiC) coated SiCp/Al substrates was investigated by electroless Ni plating process, and the microstructures of the coating......
by NdF3-LiF-Nd2O3 melt was studied using sessile drop technique in this paper. Wetting experiment was carried out under inert atmosphere at 1050 °C. Chemical reactions which occurred on the solid-liquid interface and solid-gas interface during wetting process were discussed by thermodynamic calculations combined with X-ray diffraction(XRD) patterns. Micromorphology and element distribution of fracture surface......

Airport Construction Project Headquarters, Hohhot 010000, China) Abstract: To investigate the deformation behavior of the subgrade subject to wetting, the large-scale model test and numerical modelling......
">Relative contact angle and heat of wetting can be used to provide a measurement of surface wettability of synthetic magnetite. The comparison between synthetic and natural magnetite in terms of surface wettability showed that, using the same kind of wetting liquid, the difference in the relative contact angle was 10° between the concentrate and tailings obtained from reverse fl otation of synthetic......
