  多层 CrAlN/SiN[sub x] 涂层的微观结构和腐蚀性能

  摘要：

  CrAlN/SiN。通过射频反应磁控溅射沉积多层。在多层中，SiN x 层厚度从 0.3 到 1 nm 不等，CrAIN 与 SiN x 的层厚比设置为 4:0.3、13:1 和 4:1。通过 X 射线衍射图、扫描电子显微镜和高分辨率透射电子显微镜讨论了 SiN x 层厚度对多层晶体行为和微观结构的影响。除了随着厚度从 0.3 nm 增加到 1 nm 将 SiN x 结构从晶体结构转变为非晶态外，薄膜还从柱状微观结构转变为致密结构。通过 Tafel 测量和电化学阻抗谱研究了涂层在 3.5 wt% NaCl 溶液中的耐腐蚀性能。多层结构细化了单层 CrAlN 中的粗柱状结构，导致微观结构更致密，并显示出更低的腐蚀电流密度和更高的腐蚀阻抗。此外，与 l CrAIN 与 l SiNx 的厚度比为 4:0.3 的多层膜相比，l CrAIN 与 l SiNx 的厚度比为 13:1 的多层膜具有相似的成分，但具有更致密的微观结构。l

  自旋密度波 Cr1−xAlx 合金系统中的异常三相点效应

  摘要：

  摘要 最近有人提出，对于 Cr 1 - x Al x 合金系统，作为 x 函数的 Sommerfeld 比热系数 (γ) 可能在 x-T 磁相图的三相点 (TP) 浓度 (xt) 处达到峰值。 . ( xt , T t ) 处的 TP 表示三个磁相变线的交点，预计不公度 (I) 和公度 (C) 自旋密度波 (SDW) 相与顺磁 (P) 相共存. 此处报告了对包含 xt 的浓度范围 0 ⩽ x ⩽ 0.034 内单晶 Cr 1 - x Al x 合金物理性能的综合实验研究，以进一步研究上述猜想和其他物理性能的可能异常行为近xt。测量值包括电阻率 (ρ)、塞贝克系数 ( S )、比热 ( C p )、霍尔系数 ( RH )、磁化率 ( χ ) 和热导率 ( κ )。除了 κ 之外，所有这些属性都描述了接近于 xt 的 x 的 SDW 起源的异常温度和浓度依赖性。本研究表明 xt 值相当接近 x

• The ternary systems: CrAlC, VAlC, and TiAlC and the behavior of H-phases (M2AlC)
  作者：J.C. Schuster、H. Nowotny、C. Vaccaro

  日期：1980.4

  Phase relationships in the ternary systems CrAlC, VAlC, and TiAlC have been investigated. All previously reported ternary H-phaseMe2AlC(Me =Cr, V, Ti) and the perovskite phase Ti3AlC are confirmed. No new ternary phase was found. At 1000°C Ti2AlC and Ti3AlC are coexistent. In addition, the H-phase was found in equilibrium with TiC1−x, TiAl3, and TiAl; the perovskite with TiC1−x, Ti3Al, and Ti (solid

  Exchange induced unidirectional anisotropy has been observed in a new bilayer system consisting of a ferromagnetic FeTaN or Ni80Fe20 film coupled to an antiferromagnetic Cr–Al alloy film. Estimates of the exchange coupling energy and magnetic anisotropy constant of the antiferromagnet are made and compared to other exchange coupled systems.

• A comparative study of CrAlN films synthesized by dc and pulsed dc reactive magnetron facing target sputtering system with different pulse frequencies

  CrAlN films were prepared using a balanced magnetron sputtering system operated in dc and pulsed condition (with different pulse frequencies), and their phase composition were then determined through XRD analysis. In order to investigate the relationship between the mechanical properties and microstructure of the films, hardness measurements were taken using a nanoindentation system. All films exhibited NaCl-type CrN structure in both dc and pulsed conditions. Plastic hardness, H-pl, of the films ranged between 15 to 36 GPa. Pulsed prepared CrAlN films showed higher hardness, higher internal stress values, and smaller grain sizes than dc prepared CrAlN film. Moreover, plastic hardness and internal stress of pulsed prepared CrAlN films increased on increasing pulse frequency. (C) 2010 Elsevier B.V. All rights reserved.

  The Al-Cr-Nb isothermal section at 1000 degreesC was studied by thermal analysis, X-ray diffraction and electron microprobe analysis. The enthalpies of formation of the different compounds were determined by direct reaction calorimetry. Results are presented and discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
• Investigation of the Al–Cr γ-range

  The range of Al-Cr between 25 and 50 at.% Cr was reinvestigated by powder X-ray diffractometry, differential thermal analysis, scanning and transmission electron microscopy. Experiments point to the existence of only one high-temperature and one low-temperature phase extending in the compositional range between about 30 and 42 at.% Cr. The low-temperature phase (gamma(2)) has a rhombohedrally distorted gamma-brass structure with alpha < 90 degrees continuously varying with the composition. This phase exhibited twin-oriented domains, which, in turn, consisted of the second-order twins. At 36 at.% Cr and below very fine and periodically arranged stripes were formed, which resulted in additional reflections in the corresponding electron diffraction patterns.
