Microstructure of a Mo-Si-C-N multi-layered anti-oxidation coating on carbon/carbon composites by fused slurryJEON JaehoDepartment of Materials Technology, Korea Institute of Machinery & Materials摘 要:A Mo-Si-C-N multi-layered anti-oxidation coating was in-situ fabricated by introducing nitrogen atmosphere during the fused sintering of Mo-Si slurry pre......
Trans. Nonferrous Met. Soc. China 22(2012) s688-s691 Microstructure of porous Cu fabricated by freeze-drying process of CuO/camphene slurry Sung-tag OH1, Si-young CHANG2, Myung-jin SUK3 1. Department... with macroscopically aligned channels was synthesized using a freeze-drying process. Camphene-based CuO slurry was prepared by milling at 60 °C with a small amount of dispersant. Freezing of a slurry was done......
and multi-fractal analysis of pressure fluctuation in slurry bubble column bed reactor WANG Xing-jun(王兴军), HU Li-shun(胡立舜), SHEN Jun-jie(沈军杰), YU Zhi-nan(余志楠), WANG Fu-chen(王辅臣), YU Zun-hong(于遵宏... under scale 1 and scale 2, and bi-fractal under scale 3-9 are effective in deducing the hydrodynamics in slurry bubbling flow system. The measured pressure signals are decomposed to micro-scale......
Development of aluminum rheo-extrusion process using semi-solid slurry at low solid fraction T. RATTANOCHAIKUL1, S. JANUDOM1, N. MEMONGKOL2, J. WANNASIN1 1. Department of Mining and Materials... slurry at low solid fractions. A laboratory extrusion system was used to fabricate aluminum rods with the diameter of 12 mm. The semi-solid metal process used in this study was the gas induced semi......

; Abstract: Porous carbon/carbon preforms were infiltrated with melted silicon to form C/C-SiC composites. Three-layer Si-Mo coating prepared by slurry painting and SiC/Si-Mo multilayer coating prepared by chemical vapor deposition(CVD) alternated with slurry painting were applied on C/C-SiC composites, respectively. The oxidation of three samples at 1 500 ℃ was compared. The results show......
Siliconizing Formation Mechanism and Its Property by Slurry Pack Cementation on Electro-deposited Nickel Layer into Copper Matrix王红星School of Materials Science and engineering,Southeast University摘 要:Silicide coating was prepared on electro-deposited nickel layer by the slurry pack cementation process on copper matrix at 1173 K for 12 h using SiO2 as Si......
of parameters of slurry-making process with rotating duct on semi-solid microstructure of A356 alloy GUO Hong-min1, YANG Xiang-jie2, HU Bin2 (1. School of Materials Science and Engineering, Nanchang University, Nanchang 330047, China; 2. School of Mechanical and Electronic Engineering, Nanchang University, Nanchang 330029, China) Abstract: Semi-solid slurry of A356 alloy was produced......
, slurry seepage, and slurry contraction. A prediction method of ground surface displacement was developed. The reliability of the presented method was validated through a comparison between theoretical.... Through analysis, it can be known that the ground surface uplift is mainly caused by osmosis of slurry and the primary influence angle of stratum β determines the influence range of surface uplift......
