A modified version of Haberland type gas aggregation source with an arrow-shaped aggregation chamber set with two magnetrons was used for the production of core@shell Ni@Ti nanoparticles. This configuration that had two separate magnetrons in one aggregation chamber gave the possibility to independently control the power to each magnetron and thus to control the structure of created nanoparticles. Furthermore, the chosen geometry resulted, under optimized conditions, in the suppression of the formation of single-material nanoparticles that is a common problem in the case of conventionally used planar arrangement of magnetrons in the aggregation chamber.

箭头形气体聚集源制备的复合Ni @ Ti纳米粒子

带有箭头形聚集室和两个磁控管的Haberland型气体聚集源的改进版用于生产核壳Ni @ Ti纳米粒子。在一个聚集室中具有两个单独的磁控管的这种配置使得可以独立地控制每个磁控管的功率，从而控制生成的纳米粒子的结构。此外，在优化的条件下，所选择的几何形状导致抑制单一材料纳米颗粒的形成，这在聚集室中常规使用的磁控管的平面布置的情况下是一个常见问题。
