Growth of La2Mo2O9 films on porous Al2O3 substrates by radio frequency magnetron sputtering

Synthesis conditions of La₂Mo₂O₉ thin film by radio frequency (RF) sputtering technique on Al₂O₃ ceramic substrates are studied. It is found that the deposition temperature and oxygen partial pressure are the most important factors for obtaining pure La₂Mo₂O₉ films. Varying both parameters, Mo-rich, stoichiometric, and Mo-deficient films are obtained. With increasing the La:Mo ratio, films become denser. A crust layer is observed on top of the Mo-rich and the Mo-deficient films. The formation of the La₂Mo₂O₉ phase is discussed with respect to the sputtering mechanism.     

Effect of Cd Addition on Superconducting Fluctuations and Mechanical Properties of Bi1.82Pb0.36Sr2Ca2Cd x Cu3O y System

A study was made of the effect of Cd additions on the superconducting and mechanical properties of Bi_1.82Pb_0.36Sr₂Ca₂ Cd_xCu₃O_y (x = 0.0, 0.15, 0.25, 0.35 and 0.55). Characterization of the Cd-samples using XRD, DTA, and SEM techniques, has confirmed that remarkably formation of low-T _c phase (2212) by the addition of Cd up to 0.35. High-resolution electrical resistivity ρ (T) data on the composition of Cd = 0.35 have been taken for investigating critically the superconducting fluctuations. Using the Aslamazov and Larkin (AL) and Lawrence and Doniach (LD) models of excess conductivity. Excess conductivity analysis shows that this composition (Cd = 0.35) is 2D in the temperature range 137.8–163.7 K and a 3D one below 137.8 K. Thus, a crossover from 2D to 3D is observed at 137.8 K. Sample microhardness and density are greatly improved by Cd-additions (0.35). This trend is probably due to the intercalation of cadmium between superconducting grains in compositions may provide a plastic-flow region that allows relaxation of undesirable stresses resulting from the grain anisotropy of superconductors.

纯镁渗锌处理表面合金化机制研究

对纯镁进行了表面渗锌处理，研究了扩渗温度及扩渗时间对于合金化渗层组织、相结构及反应层连续性的影响。结果表明：扩渗温度的选择有一个合适的范围，温度过低，扩渗速度太慢甚至Zn元素原子的能量达不到其激活能，不能产生活性原子，扩渗过程无法进行。温度过高虽然有利于形成合金化渗层，但会使基体晶粒粗化，甚至改变整个基体，而且，温度过高不利于反应层（金属间化合物区）的稳定：扩渗时间的延长会促使Zn的进入量和金属间化合物的生成量增加，并削弱晶界扩散优势的影响，最终使固溶层和反应层趋于均匀化。要形成连续的反应层，扩渗温度应控制在400℃～420℃，相应的扩渗时间为8h以上。
