More than hundred diffusion couples between p- and n-type skutterudites and various materials were prepared and interaction zones were investigated after heat treatment at 600 °C for 1100 h. The constitution of reaction/diffusion zones was discussed in terms of: (a) atom site preference in the skutterudite lattice, (b) phase equilibria in multicomponent systems and (c) particularities of the crystal structure of intermediate phases. It could be shown that phase composition and thermo-mechanical properties of bonding can be engineered by chemical substitution. The results obtained allowed the determination of several necessary criteria for the development of chemically and mechanically stable diffusion barriers/couples for skutterudite based thermoelectric (TE) modules.

方钴矿与接触材料的相互作用：冶金分析

制备了 p 型和 n 型方钴矿与各种材料之间的一百多个扩散对，并在 600 °C 下热处理 1100 小时后研究了相互作用区。反应/扩散区的构成从以下方面进行了讨论：（a）方钴矿晶格中的原子位置偏好，（b）多组分系统中的相平衡和（c）中间相晶体结构的特殊性。可以证明，键合的相组成和热机械性能可以通过化学取代来设计。获得的结果允许确定几个必要的标准，用于开发基于方钴矿的热电 (TE) 模块的化学和机械稳定的扩散屏障/偶。
