, ZHENG Shao-hua. Analysis of drying mechanism on the tape casting laminar green tape of Mo-(Fe-B)-Fe mixed alloy powders[J]. Journal of Ceramics, 2002, 23(4): 211-216. [53] Salam L A, Matthews R D......
高温合金,长时间在高温,高应力等复杂环境服役的过程中会形成大量有害的拓扑密排相(Topologically closed packed phase,TCP相),从而严重地降低合金的高温蠕变与抗氧化腐蚀性能. 假如高温合金的设计研发仍然仅仅依靠长期积累的经验和凭借科研人员的专业知识与能力,采用传统的耗时费力的试错法(Trial and error)来完成,将不能摆脱一种新材料从初始研发到最终应用通常...析,可以获得临近合金成分的相平衡关系.扩散偶法对每一个扩散偶的表征分析可以获得扩散偶成分范围内的相平衡关系.区别于平衡合金法和扩散偶法需要制备多个试样的特点,扩散多元节方法可以在一个试样上实现比前两者更大成分范围内的相平衡关系,是一种高通量的合金制备和相图测定方法. 1.1 平衡合金法(Equilibrated alloy) 平衡合金法是一种传统的并被广泛采用的相图测定方法.合金法的一......
Open circuit potential measurement A two-electrode electrochemical cell with silver/ silver chloride electrode was used as the reference electrode. The measurements of open circuit potential (OCP) were... performed at ambient temperature with Autolab PGSTAT 30 ECO CHIMIE potentiostat and electrode cell containing 200 mL of electrolyte, with and without TTD compound. A graphite rod was used......

crystalline size, lattice constants and unit cell volume also increased up to 4% of cadmium doping. Energy gaps of the samples were determined from the ultraviolet-visible absorption spectrum as well... technique increase the efficiency of the dye-sensitized solar cell [11]. Usually, Cd doping results in decrease in energy gap of ZnO. But, it has been observed that 1% Cd doping increases the energy gap......
in excess to dissolve silver sulfate precipitate (ammonium electrolyte). Silver was electrodeposited by a potentiostatic regime of electrolysis, in an open cell of a cylindrical shape at the room... close to the cell wall. The working electrode was situated in the middle of the cell, while the tip of Ag reference electrode was positioned at a distance of about 2 mm from the surface of working......
be mainly divided into five types: 1) carbon based materials; 2) metal oxides and sulfides; 3) alloy-based materials; 4) titanium- based composites; 5) organic compounds [6]. Graphite, the most...]. Although metal oxides [9, 10] and sulfides [11–13] along with alloy-based materials [14–16] have high capacity, they still face a number of issues such as poor initial Coulombic efficiency and inferior......
