and carbonization processes in the hydrothermal reaction of glucose were analyzed. A schematic model of the wear surface of the Al/APC composites was established and the wear mechanisms were discussed.关键词:......
synergistically.In the pyrolysis process,it is divided into two steps:the first step is the breakage of large molecules to small molecules;the second step is the gasification and carbonization of small molecules......
products during carbonization. A part of gas products agglomerate to fluid drops containing C, P, O, H, etc. while blocking at the wall of the crack, and then the drops convert to carbon ball with high carbon content after carbonization, with diameter of 2-4 μm. Other gas products try to release from composites. The gas pushes the tiny cracks to spread when there is no way to release until the crack......
silicon substrates with the orientations of (100), (111), (110) and (211),respectively. Even though an initial carbonization was carried out to reduce the large lattice mismatch, residual stress could......
基体炭对反应熔渗法制备的C/C-SiC复合材料性能的影响冉丽萍1,刘亦奇2,杨琳1,易茂中11. 中南大学粉末冶金国家重点实验室2. 中南大学材料科学与工程学院摘 要:以炭纤维针刺整体毡为预制体,分别采用化学气相渗透(chemical vapor infiltration,CVI)法,浸渍炭化(Impregnation and carbonization,I/C)法以及CVI与I/C相结合(CVI&I/C)的方法制备C/C坯体,坯体中的基体炭分别为热解炭,树脂炭,热解炭和树脂炭共存体,再通过反应熔渗硅(Reactive molten infiltration,RMI)获得C/C-SiC复合材料,对该材料的组织结构,力学性能和抗氧化性能进行研究.结果表明:C/C-SiC复合材料的相组成为SiC......
rates were achieved for the briquettes kept at 1250℃ for 15 min during the direct reduction process. SEM observation indicated that the rates of indirect reduction and carbonization became dominating......
were compared by changing the SAC-Melamine ratios. The effect of carbonization temperature on the modification was also investigated. Surface chemistry and adsorption properties of the modified......
the accelerated carbonation process.In the accelerated carbonation process,penetrative protective agent improved the carbonation resistance of the higher compactness concretes but accelerated the carbonization......
hydrothermal carbonization(HTC), ultrathin Te nanowires were adopted as templates and glucose as the carbon source, and TiO2 was decorated on CNF via the hydrolysis of tetrabutyltitanate in the presence......
